It’s been a while since I last played Open Transport Tycoon Deluxe. Really nice game which now also available in Fedora through YUM (yum install openttd*).
New version has new signals (path signals) which makes it really better. One thing to remember: since path signals are shown only to one direction, there are two types of those signals: one way and both ways. In case of one way – trains can go in back direction of the signal, which (eventually) led me to a train crash :(((( So from now on I prefer to put two ways signals in usual cases just to be sure :)
