EXHIBIT_C_-_JMMU_MAT54_MAT56__MAT58___AT60_CROSS-SECTION.pdf

This document is a technical cross-section diagram for the JMMU rail line project (Models MV54, MV56, MV58, and MV60). The diagram illustrates a standard railway track profile and subgrade construction specifications at a 1:40 scale, designated as Section D.

The cross-section depicts the following key construction elements: a service road with a minimum 4.4-meter width, a 1% slope on the front approach (12.2-meter front target berm), and timber ties measuring 175mm × 225mm × 2.6 meters with a minimum one-timber sub-grade setup consisting of 10 timbers. The ballast layer specifications include a 250mm Grade 2 ballast layer with 150mm track ballast, and a highlighted yellow annotation requiring removal of 10-inch ballast and 1-inch of subgrade and ballast. A 2% slope is specified on both sides of the track, with a 300mm compacted subgrade (90% compaction) brought to grade before pile driving. Additional features include a geogrid filter fabric layer, 300mm compacted subgrade with 125mm Grade 6 and 75mm Type AA materials, and HP 200×54 steel H-piles to be driven 2.0 meters below the target subgrade elevation. The profile includes reference points for vertical control and notes regarding track and tie specifications by others, with the document cross-referencing target data sheet C-199.
