All trains waiting to be pushed uphill use track number 1 at Laufach station. In fact, track number 4 was often used. My suggestion is that some trains waiting to be pushed uphill use track number 4. Two current trains could be waiting at the station. My next suggestion is to add the Falns railway coal wagons that we obtained from the DLC DB155. These cars were often run on this railway. This would add realism to the traffic on the DLC MSB.
I'm all for extra layers and service variety on existing (and of course future) routes! Maybe they can look it, as the preserved collection crew is now focusing on RT and MSB if I recall correctly.
Excellent idea and the way you play these trains with two locomotives is that you activate banking mode on the rear locomotive. There is one here in-game that is actually 09:49 Aschaffenburg-Gemünden Freight train DB86108. Speaking of that train it has Zacns tanker wagons Laaers 560 motorail wagons Haabiins paper roll Wagons and the steel coil transporter wagon Shimmns 708.
