Can anyone help me iam looking for a website which will tell me what all the railway singals mean.?

Answer 1

On the London Underground signals are automatic or sem-automatic.  The auto signals operate where there are no junctions and work fully automatically from the track circuits.  The axles on the train short out the low-voltage track circuit in the running rails causing and armature to fall (by gravity) making a connection to the red signal of the section in the rear.  As the train passes out of the section the low voltage restores livening an electo magnet which lifts the same armature thus connecting to the green aspect.  Signals have always had the green at the top in parrallel with the action in the signal relay.

Semi automatic signals are similarly based on track circuits but with circuits to levers controlled by the signaller in conjunction with points defining the required route.  Nowadays most of this action is computer controlled but the principles are the same.

Calling on signals are semis. that allow one train to draw onto an occupied section.  (Used on the now-rare process of coupling up or to enter an occupied section).

'X' Signals are the last auto before a semi. section to which special rules apply.

Some of the newer lines have automatic train swith different signalling processes.

As I have retired from the railway some time now there may be updates I am unaware of but I guess the principles haven't altered.

http://www.lundsten.dk/us_signaling/aspe...   you didn't say where you are located but this link will show you some of the ones used by u.s. railroads   Also the site www.trainweb.org has a rule book download for the general code of operating rules which the class one railroads in the u.s. use.There is a lot of info there about train operations

Answer 4

UK Railway signals fall into 3 catagories, Track Circuit, Absoloute Block and Shunting signals.  On top of that there is the differances between South style signals and the rest of the UK, Token Block working, Single Line Working with Hand Flags, Shunting Work Signals and Platform Work Signals, which fall under a different area of the Rules and Regulations of the Railway.

If you are lucky and talk to the staff at your local station where they dispatch trains nicely, they may let you look or copy the sections in the Railway Rule Books Concerned.

Good Luck.
