SCOPE OF WORK

1.0 Project Description/ Summary

This project will provide for the removal and replacement of the wooden cab on Denver and Rio Grande Western Railroad Model C-16 Steam Locomotive #278 (National Register ID # 09000223). This locomotive is currently on display on a trestle at the Cimarron district of the park and is a popular visitor destination. The locomotive has experienced significant deterioration of the wooden cab due to exposure to the elements. The project will provide for the removal of the locomotive from the trestle using a contracted crane company. Once removed, the locomotive will be transported to the fenced storage yard at Cimarron and placed on the tracks within that yard. At that point, the cab will be removed from the chassis and transported to a qualified contractor facility to be reconstructed. Due to the condition of the existing cab, it shall be used as a template/model only and a new cab will be constructed. A new locomotive cab will be constructed by a historic rail restoration contractor. The new cab will be constructed using materials as defined in this specification. Additionally, the new cab will be painted and accurately lettered according to the attached specifications. Once the cab construction has been completed, the restored locomotive cab will be transported to the park and installed on the locomotive chassis which will remain in the fenced storage yard at Cimarron. Once back on site, the new cab will be reinstalled on the locomotive chassis and placed back on the trestle by a contracted crane company. Essentially, this project is composed of three main elements:

1. Removal of entire locomotive from the trestle by a heavy crane and transporting the locomotive to the tracks within the fenced storage yard at Cimarron (locomotive tender and other rolling stock to remain on the trestle). Once at the yard, the locomotive will be lifted onto the tracks for temporary storage during the next phases of the project. This will be followed by unbolting the cab structure and lifting the cab off the locomotive chassis and onto a transport trailer/vehicle for disposal or as a pattern for the new cab construction.

2. Cab will be transported to the historic railroad restoration contractor’s facility. Construction and painting/finishing/lettering of new locomotive cab according to specifications included in this package will be completed.

3. Transport of new cab cack top the Cimarron yard where it will be reinstalled back onto the locomotive chassis through the use of a heavy lift crane. At this point, the entire locomotive will be lifted onto a transport vehicle and carried back to the trestle where a heavy lift crane will be used to place the entire locomotive back onto the trestle and recoupled to the rest of the display pieces on the trestle.

2.0 Equipment

A. Mobile Heavy Lift Crane: Must utilize a professional crane company that is fully licensed and insured for equipment operated. Crane shall have lift capacity of at least 60,000 pounds. All lift webbing, cables or other lifting hardware shall be undamaged and possess a lift capacity of at least 60,000 pounds.

B. Transport Vehicle and/or Trailer: Must be adequate to safety transport the locomotive approximately 1 mile to the fenced yard/storage track. Weight carrying capacity of at least 60,000 pounds will be necessary as well as adequate tie-down mechanism to ensure safe transport. Since the old cab old cab is likely to be used as pattern, it will need to be transported to the contractor’s facility. A Vehicle/Trailer shall be equipped with adequate tie-down mechanisms to secure the cab for transport without inflicting new damage during transport will be required. This transport vehicle/trailer should have a carrying capacity of at least 15,000 lbs.

C. Contractor will provide all tools and equipment needed to disconnect the locomotive cab from the chassis as well as equipment to hold and stabilize the cab during crane rigging in preparation for lift cab clear of chassis.

D. Contractor will provide all tools, equipment and materials to build a new replica cab for the locomotive according to specifications provided in this document as well as paint and letter the cab in a historically accurate paint scheme as it is now.

E. Transport Vehicle and/or Trailer for newly constructed cab: Must have an adequate cargo carrying bed and a weight carrying capacity of at least 15,000 pounds. Vehicle/Trailer shall be equipped with adequate tie-down mechanisms to secure the cab for transport without inflicting damage upon completion and transport to the park.

F. Contractor shall provide mobile heavy lift crane to safely reinstall the new cab back onto the locomotive chassis. Contractor will provide all tools and equipment to reinstall the new cab onto the locomotive chassis. Contractor shall provide a crane with a lift capacity of at least 60,000 pounds to load the locomotive onto a contractor provided transport vehicle capable of carrying at least 60,000 pounds to safely transport the locomotive approximately 1 mile back to the trestle.

G. Mobile Heavy Lift Crane: Must utilize a professional crane company that is fully licensed and insured for equipment operated. Crane shall have lift capacity of at least 60,000 pounds. All lift webbing, cables or other lifting hardware shall be undamaged and possess a lift capacity of at least 60,000 pounds.

3.0 Objective(s)

The objective of this project is to safely remove locomotive # 278 from the display trestle to be placed on a transport vehicle. The locomotive will be transported to the fenced storage area/ tracks at Cimarron. Once there, the locomotive will be placed on the storage tracks where the cab will be removed and ferried to a qualified historic rail restoration contractor where it will be used as a pattern for a new cab. Any salvageable/reusable parts such as metal cab sides can also be stripped off the old cab and reused. New cab components will be fabricated using historically appropriate materials. Upon the completion of construction and finishing, the new cab will be transported to Cimarron and reinstalled and secured on the locomotive chassis. The entire locomotive will then be transported back to the trestle and reinstalled onto this structure.

4.0 Background

The narrow-gauge Locomotive at the Cimarron interpretive display is deteriorating due to exposure to the elements. The locomotive, which was built in 1897 by the Baldwin Locomotive Works has suffered considerable deterioration and rotting of wooden cab components and paint has begun to fail on most wooden surfaces. The cab roof has lost virtually all its water-proofing coating and the roof slats have rotted and begun to fall off into the Cimarron River below the display trestle. Most of the locomotive cab shows some level of rot and deterioration on both exterior and interior surfaces. Unless action is taken to stop this deterioration and return the locomotive to good condition, an important historical piece will be lost to the public without a much more significant investment than is currently needed.

The Steam Locomotive is displayed in situ on an historic train trestle along with a Locomotive Tender, Box Car and Caboose. The trestle is free standing over Cimarron Creek (100 ft. drop) and does not touch either embankment. While this prevents vandalism and unauthorized entry, access for maintenance is extremely hazardous, difficult, and for the most part not attempted. This project would provide removal of the locomotive from the trestle trestle and facilitate subsequent reconstruction/restoration followed by reinstallation of the cab and locomotive.

The preservation of this resource provides a connection between the mission of the Recreation Area and the surrounding communities. The operation of the Denver & Rio Grande Western railroad through the canyon was an important part of the history and economic development of southern Colorado from the front-range to the Utah border. From circa 1897 to the 1940’s, this railroad equipment brought miners and settlers to the area, and transported livestock, lumber, and minerals from the region to markets in other parts of the nation. The fact that most of the cars on display at Cimarron actually carried freight and passengers between the local communities provides a link between current residents (perhaps some who actually rode this train as children) and the history of the area. If the train resources are lost due to the extremely harsh environmental conditions, there will be little to no attraction for visitors to the area.

5.0 Project Work / Tasks (Primary Proposal)

1. Provide crew to be placed on trestle to rig the locomotive for trestle removal by heavy mobile crane:

a. Provide crew and equipment to raise locomotive off the trestle and load onto an appropriate transport vehicle for secure transport to the fenced yard/storage tracks at Cimarron. Provide crew to place the locomotive on the storage track as well as disconnect the cab from the chassis for transport to a historic railroad equipment restoration facility for use as reference and pattern during construction of new cab.

* Due to current condition of cab, it must be rigged to maintain integrity during lift and transport. Since a complete rebuild of the cab is going to be necessary, this is primarily to prevent the cab from coming apart during lift and to preserve any reusable and undamaged components such as original mounting brackets for use in the new cab.

2. Provide all tools, equipment, facilities, and materials to construct and finish a new locomotive cab:

This will replace all damaged and rotted cab components and return it to good condition. This shall include refinishing/repainting all components in historically accurate colors and finishes and applying all appropriate lettering.

a. The entire existing wood cab is extremely deteriorated and should be considered structurally unsound. Persons should stay off the roof of the cab.

b. The new cab should be constructed in the same manner as the old cab. White Oak is to be used for cab construction. Although this is not the original cab construction material, it does represent the material used on the cab for the majority of the locomotive’s service life and will endure exposure to the elements for a much longer period than the existing white ash cab. Corroded fasteners from the old cab should be replaced. The large cast washers at the corners of the cab should be sandblasted and repainted as should the various original brackets installed in the cab. The entire new cab should be painted per recommendations in this document. Mortise and tenon joints are used throughout the cab. Also, special attention must be paid to all the bevels and finishing details used on the cab. A contractor with extensive woodworking experience is recommended for the building of the new cab, windows and doors. The Plexiglas used in all the windows and doors on the cab has been blasted opaque by the wind and all should be replaced with new Lexan. When constructing the new windows and doors, the frames should be constructed so that the permanent window retaining shoulder is to the outside and the replaceable ¼ round that holds the glass in place is on the interior side of the frame. When installing Plexiglas into windows and doors, the glass should be sealed to the frame with a large bead of glazing compound (used in a caulking gun) and secured with several steel glazing points. This way, if the 1/4 round wood strip falls out, the Plexiglas will remain in place. All new windows and front doors, even those that are movable, need to be permanently fastened and sealed shut with 50-year paintable caulk to keep the weather out. For a static display, it is not necessary to have opening windows and doors. The rear cab doors can be left usable to access the cab interior but should be sealed to keep insects out and lockable to prevent vandalism.

* The cab roof should also be replaced with tongue and groove fir or pine siding. The cab roof bows and curtain mounting blocks should be fabricated of white oak. The cab roof is to be covered with black painted sheet metal to protect new roof from water damage. The cab roof vent, while in place, is a dummy vent. This is good as there is no need for a hole in the roof that would just let moisture and insect into the cab. The new cab should have an identical dummy vent. The cab roof metal needs to be replaced with new metal that extends over the edge pieces and is fully sealed from moisture. Special care needs to be taken to ensure that the new roof is fully sealed against the weather. The metal used for the cab roof should be of the type that will hold paint. The new cab roof should be covered with 15-pound tarpaper before installing the new metal roof. The fake cab vent should be reinstalled on the new roof with the screw holes fully sealed. The roof grab iron should also be sealed with 50-year caulk. On most cabs of this type, the electrical conduits also went across and through the roof at several points. This conduit has been removed and placed inside the cab. While not historically accurate, this is better suited to help keep the cab from receiving moisture damage.

* The metal plates on the front and rear of the cab help seal the cab around the boiler and the back of the firebox. These metal pieces appear good but could be badly corroded. They will have to be sandblasted and repainted. The cab floors are also deteriorated. The floor consists of a ¼” metal sub plate with a tongue and groove siding fir or pine floor on top of that. The metal trim strip that runs along the bottom outer edge of the cab is riveted to the floor plate. This trim strip needs to be saved, sandblasted and re-riveted to the new floor. The lower half of the cab sides are also covered with sheet metal. This was done by the railroad when the cab sides started to fall apart as it was easier than rebuilding the cab. These metal panels were present on the locomotive during the 1940’s and should be reapplied over the new cab sides. The metal will need to be sandblasted and repainted. The metal floor is corroded and should be replaced. The wood floor should also be replaced with tongue and groove siding.

* Cab painting and lettering. Painting procedures are listed below. This section covers the final, finish painting of the cab. It is required that the entire cab be painted with two final coats, including the top and under frame. The recommended paint is gloss black Acrylic Modified Alkyd Enamel. The current paint and lettering scheme is assumed to be the one desired on the rebuilt cab. Please note that although the current engine lettering is white, in the 1930-early 1940’s era some engines were lettered with silver paint. Stencils of lettering may have to be created using the existing lettering before sandblasting begins. If additional lettering stencils are needed, contact the Colorado R.R. Museum. Painting Procedures. The painting procedures listed have been developed while rebuilding many pieces of historic railroad equipment over the last twenty years.

* All new wood should have woodworking operations completed (if possible) before painting. Some pieces will need to be cut to fit and then have the last area painted. All new wood should then be painted with a primer made from the final paint color and 20% boiled linseed oil. It is highly recommended that all pieces of wood be painted before assembly.

* Painting metal: All reused metal should be sandblasted to bare metal. All new metal should have the oils and scale cleaned off. Then, the metal should be painted with Rustoleum (or approved equal) metal primer. After this is dry, the metal should be painted on all sides with the final color. This is necessary because metal primer, when left in contact with wood, will cause corrosion. Also, rusted metal left in contact with wood (especially white oak) will cause the wood to rot. It is highly recommended that all metal pieces be painted with the final color before installation. Painting Bolts: It is recommended that plain bolts, nuts and washers be used so that they can be painted with the final color. Bolts coated with zinc plating can be used, but the zinc is so thin that they will corrode after a few years. Paint: It is highly recommended that all paint used on the equipment be oil based. A marine based paint should be considered for the equipment. This will improve weather-proofing. Metal Primer painting procedures are covered in recommendation “painting metal”. The paint used for the next coat above the primer for metal should be an acrylic modified alkyd enamel and the use of lacquer thinner is required to clean or thin it. This paint has performed very well in the outdoor environment and even works well on wood.

* Wood Paint: A paint that is very good for wood a high-gloss oil enamel, which must be cleaned and thinned with mineral spirits. The paint used should hold up well for ten or more years. Finish Painting: After the rebuilding of the equipment is completed, a final series of finish paint coats should be applied. For all gaps, joints, windows, and other potential areas that need to be sealed against the weather, the use of 50-year paintable caulk is highly recommended. The caulk is best used between layers of paint as it sticks better to paint than unpainted surfaces. It is recommended that the equipment be sprayed with an airless paint sprayer as this type delivers more paint and uses high pressure to force the paint into all cracks and gaps. For metal equipment, which should receive two final coats, the paint should be sprayed once a day for two consecutive days. For wood equipment, which should receive at least three final coats, the paint should be sprayed once a day for three consecutive days. If the painting is not done on consecutive days, the preceding coat may dry enough to prevent the next coat from adhering to it.

Lettering: The lettering should be done with a professional lettering paint. D&RGW stencils may be available from the Colorado RR. Museum.

4. Provide crew tools and equipment to transport, rehabbed locomotive cab back to the Cimarron and lifting the cab back onto the locomotive chassis using a heavy lift crane and rigging capable of safely lift and accurately placing at least 15,000 pounds. Reinstall all hardware to resecure the cab to the locomotive chassis.

5. Provide crew tools and equipment to load and transport locomotive back to the trestle where it will be reinstalled back into its place on the trestle with a heavy lift crane capable of lifting at least 60,000 pounds.
