It's not that unusual for a train to get stopped at a red signal in CTC territory and the Rail traffic controller can not clear the signal for unknown reasons so written permission is given to pass the signal. It could happen on single track , 2 or more tracks... The RTC will indicate the signal number, route Train designation ,
A crew member is required to take the switch off power , mesh the points and line the switch for the route given, could be one switch or maybe 4 or 5, The switch is then put back on power as the trucks of the engine occupy the points...
The train must now proceed at restricted speed until the next permissible signal. Crews must now be on the look out for a broken rail. improperly lined switch , Being able to stop with in half the range of vision and in no case exceeding 15 MP in ABS territory.
Having said that...If the Signal are suspended? What type of track permits are issued??? Do crews just run absolute stop signals...???
It appears the switch from the main to the track where the freight was parked was lined and lock for the service track.
