U-Bahn Frankfurt II help needed

  • Today I purchased U-Bahn Frankfurt II and discovered that the HUD does not work with the engines that are included with the package. I could find nothing regarding this on the Just Trains website on this package and there is nothing in the manual to indicate that the HUD will not work with these engines. I have submitted a ticket to support but was wondering if anyone else has experienced this and if there is a solution. I like the routes but like driving the trains using the HUD instead of using all of the switches, etc in the engine cab.
