Jamaica Training Aid Practice Test

This question tests how Jamaica Storage Yard tracks are laid out and how their numbering works. The yard runs tracks from south to north and numbers them 1 through 17, but there is no track 11. A switching lead is present, which lets yard locomotives move cars between the main line and the yard. So the description that matches this setup is tracks numbered 1 through 17 from south to north, with track 11 missing, and a switching lead. The other options would imply the wrong numbering direction, the existence of track 11, or no switching lead, which doesn’t fit the actual layout.
