Number of Tracks Plaque: Meaning and What to Do

The white plaque with a number above the word TRACKS is mounted below the crossbuck at a railroad crossing that has more than one track. The design shown says 3 TRACKS; the number is whatever the crossing actually has. It tells you that when one train has passed, another may be coming on a different track.

The sign

Number of Tracks Plaque

  • MUTCD R15-2P
  • Horizontal rectangle plaque
  • White with black legend
  • Regulatory sign

The plaque addresses a specific crash: a driver waits for a train, watches it clear, and pulls forward into a second train hidden behind the first. The more tracks, the more likely that a train you cannot see is occupying one of them.

What to do

What to do when you see the number of tracks plaque

After a train passes, do not move until you can see clearly down every track in both directions. If the crossing has gates and lights, wait until the gates rise fully and the lights stop flashing; a gate that stays down after one train passes means another is coming. Never drive around a lowered gate.

The signs it is confused with

Tests pair it with the crossbuck it hangs under and with the round yellow advance warning sign. The plaque adds no new rule; it tells you how many tracks the existing rules apply to.

Questions

Questions about the number of tracks plaque

What does the tracks plaque mean?

The crossing has the number of tracks shown. After one train passes, another may be approaching on a different track, so check every track before you move.

Where is it mounted?

Directly under the crossbuck at crossings with more than one track. A single-track crossing does not carry it.

Why would a second train be hidden?

The first train fills your view. A train on the far track, moving the opposite direction, can be completely behind it until the first train clears.

What if the gates stay down after a train passes?

Stay stopped. A lowered gate means the crossing is still active, usually because a second train is coming.

How does this plaque appear on the written test?

In multiple-track crossing scenarios that ask what to do after a train has passed, and in recognition questions about the railroad sign family.
