Version 2 of KVB Hochflurlinien was released yesterday by Kleinkoeln. It includes all or part of several tram lines in Koln modeled accurately, and a grade separated line from the central subway of Koln to the Hauptbanhoff in Bonn. I successfully downloaded and installed it yesterday. I operated the included two-car tram train from Bonn to Koln and am very impressed at the attention to detail and the scenery. There is an occasional minor glitch (sound disappeared for a few seconds in tunnels) but on the whole it is in the same league as other top freeware routes. If you had version 1 or like running trams in a variety of ROWs this one is for you. Get it at
