SimSig is so good that Railtrack, as they were then, bought an enhanced version of Didcot (Swindon B IECC) for use as signaller training. The following are also aviable: KingÆs Cross, North London Line, Swindon, Southampton, Stafford, Waterloo, Liverpool Street, Didcot & Westbury û all free!
To download, go to www.simsig.co.uk. To get the Bristol beta, go on to the Forum and then Bristol PSB board. Open the Beta available! thead to find a link to the download. Just remember that it is a beta and therefore does have bugs in it!
