My dad bought this game in the 80s and it's the one game from my childhood that stands out as causing more fun and bad tempted havoc than any other so when I saw that it had been re-issued I had to get a copy to share the fun with my own family. The basic idea is to use the railway network as a game grid. You draw six random "souvenir" cards which are the places you have to visit before returning to London. You travel around the network getting to places and once you have done them all you go home, 1st back to base is the winner. If that was all there was it'd be pretty boring but there are two extra factors, signals and cards. You can place two signals each and a signal requires a throw of a six the break and cards are drawn each time you change networks (FGW to GNER etc) and can either be great "you are minister of transport, rearrange all the signals" to awful "ask each of your fellow players where you should be sent to". These two factors totally change the game and make it extremely strategic. You can't let on where you are off to so that people won't signal it to death and if you annoy the rest of the players too much you can find yourself snatching defeat from the jaws of victory and being sent to Stornoway behind 4 signals when you where on the home leg. It's this element which provides the fun, unexpected victory, grumpy stormings off etc, all wonderful family fun.
