The West Layup trails into which mainline and near which signal bridge?

• A. Mainline 1, just west of the Meathouse signal bridge
• B. Mainline 2, east of the Meathouse signal bridge
• C. Mainline 1, east of the Yards signal bridge
• D. Mainline 3, west of the Meathouse signal bridge

Answer: (A)

This item tests how the layup track feeds into the mainline in relation to signal infrastructure. The West Layup is designed to exit into Mainline 1 at a specific reference point so trains coming off the layup can merge with the mainline under proper signaling. The correct description is that the West Layup trails into Mainline 1, just west of the Meathouse signal bridge. This placement aligns the layup’s end with the western side of the Meathouse bridge, providing a clear, protected entry point into Mainline 1. The other options place the entry on a different mainline or near a different bridge, which does not match the established track layout and signaling reference for the West Layup.
