Johnson Avenue Yard bumping blocks protect which end?

Johnson Avenue Yard bumping blocks protect which end?

• A. The west end of tracks 1-4
• B. The east end of tracks 1-4
• C. Both ends of tracks 1-4
• D. Between tracks 3 and 4

Answer: (A)

Bumping blocks are safety devices placed at the far end of a track to stop equipment from rolling beyond and to absorb impact if something reaches that end. They define the end that’s protected. In Johnson Avenue Yard, the blocks for tracks 1 through 4 are located on the west end, so that end— the west end of those tracks— is what they protect. The protections aren’t at the east end or between tracks, so those ends aren’t safeguarded by these blocks.
