What are the different classes of stations?

19-07-2019

IR's classification of stations is linked to their rules for block system working. Class A: Such a station is one where the Line Clear indication for the block may not be given unless the line where the train is to be received is clear at least for up to the starter signal (or, in some cases, for at least 400m ahead of the home signal). These are stations where many trains normally run through without stopping at a high speed, hence the need for the safety margin to prevent accidents in cases of trains overrunning signals. Class B: Such a station is one where the Line Clear indication may be given before the section of the line within the station has been cleared for reception of a

Since about 1999, handled radio sets (walkie-talkies) have been issued to most drivers, guards, and other staff on the move. These handsets usually have a fairly short range (a kilometer or so). VHF radio sets have been installed in the loco cabs for a few important trains such as the Grand Trunk Express, Tamil Nadu Express, and the Rajdhanis and
