Reply to "I Need Help! How do you wire an MTH Railking O Scale 7 Light Signal Block #30-11013 with Isolated Rail and/or Relay, Not with an ITAD?"

For what it's worth, a PRR signal displaying 3 horizontal lights means STOP. A signal displaying 3 horizontal lights with a single light below them means STOP AND PROCEED. A train approaching a STOP AND PROCEED signal should stop, then proceed at restricted speed (20 mph or less). A STOP signal is like a red traffic light: stop and wait until it changes, whereas a STOP AND PROCEED signal is like a stop sign.
