Block Signals Used on Norfolk and Western Safeguard Against Wrecks
The Norfolk and Western has the automatic signals for movements of trains completed and in operation from Roanoke to Christiansburg. The signals are about a mile apart and when a train passes a signal it is automatically thrown to danger and remains in that position until the train passes the next signal ahead when the first signal again goes back to "clear track."
The normal position of the devices signal "clear" and they stand at danger only when the block is occupied by a train. When a train fiends a signal at danger it must come to a stop and then proceed carefully looking out for a train ahead.
The trainmen are very much pleased with the signals. Telegraph operators are rapidly being displaced by the "iron operators."
