APM Maintenance Facility Concepts 1b - 2 revised 2.27.25.pdf

The document appears to be a preliminary concept analysis for an Automated Guideway Transit System (AGTS) Maintenance Facility at Denver International Airport (DEN), presenting two potential design configurations for expanding the existing maintenance facility. The first concept involves a ROM (Rough Order of Magnitude) cost of $37M with a facility size of 29,200 sq ft, featuring 7 four-car train configurations, 282 four-car trains in service, 85 cars in heavy maintenance, and 51 four-car trains in hot standby. This concept emphasizes a compact design with one heavy maintenance line, easy-to-expand storage lines, and Concourse D expansion potential.

The second concept expands on the first, with a ROM cost of $48M and a facility size of 38,000 sq ft, maintaining similar train configuration metrics. This iteration proposes keeping the heavy maintenance area in its current location, adding only one additional switch at the test track, and providing direct access for 4-5 cars in heavy maintenance. The document suggests this option is the "easiest to implement" with concentrated work area in the existing building. Both concepts address the growing needs of the AGTS fleet, with considerations for operational continuity, maintenance efficiency, and potential future expansion, though Alstom HQ reportedly has reservations about the transfer table in the first concept.
