Joe Posted June 22, 2010 Share #3 Posted June 22, 2010 They are repeater signals. The signal they repeat is generally located behind a blind curve. Note that the signal plate will say REP. Link to comment Share on other sites More sharing options...
MTR Admiralty Posted June 23, 2010 Share #4 Posted June 23, 2010 There are always signals on the right side.But sometimes there will also be one on the left.Why is that? And does the T/O have to follow those? Usually when the train is curving towards the right, a signal, which is usually on the right hand side (clearest to the T/O) would be blocked. So a signal is placed on the left hand side of the tunnel acts for the regular signal on the right. These guys are called repeaters. Otherwise, the T/O would not be able to see the signal on the right and stuff can happen. Link to comment Share on other sites More sharing options...
