Interested to know. If DTG chose 3 main routes. GWE, MSB and NEC, and every other UK/GER/U.S cycle these routes were expanded, picking up new trains, Depots, Yards,industries and points of interest as the network got bigger. Whilst inbetween these cycles maybe we got a route from another Country or we got the 20 mile switcher routes. By now we could be talking London-Exeter, with Plymouth/Penzance coming up in the next 12/18 Months. NEC could be heading out towards Boston or Washington and we could have a Main Spessart Bahn route big enough to incorporate ICE trains.
