SAFE or DERAIL?

Quiz Instructions

As a train engineer, your job is to determine whether the train you’re operating will run through the points of the turnout you’re approaching. First, determine whether you’re on the straight or divergent track. Then use the switch position indicator to make sure it corresponds to the track you’re on. If it doesn’t match, you will DERAIL; if it does, you are SAFE.

This quiz demonstrates a comparison of traditional SPIs and our patent-pending SwitchPath Lights system.

Color Reference (Traditional Targets)

  • Green = straight track position
  • Yellow = divergent track position

SwitchPath Lights

  • The track with the illuminated lights is the track that is SAFE to travel
