Hello! So like me and many others, we love your passenger trains, and sometimes we like to create consists seen from excursions, executive trains, inspection trains, etc but we only have a handful of passenger rolling stock, mostly from G-TRAX, and a few other DTG train packs like the Great Northern Empire Builder. What this pack would do is just add some cars that we see on like I mentioned earlier, executive trains, inspection trains. 1. Power Cars These cars well, provide power for the passenger cars, "Locomotive auxiliary generators provided 32-volts of electrical power for the passenger cars that could be “stored” for short periods of time in batteries underneath each car. As Union Pacific’s passenger equipment was modernized and the need for electric power grew, steam generator cars were rebuilt into diesel-electric generator cars that provide electricity to the entire train. Each passenger car is connected to the power car using a series of “jumper cables” between each car. Some of Union Pacific’s passenger cars are equipped with their own electric generators, allowing them to operate without a power car. " 2 Forms of power cars for this pack: 1st Style of Power Cars: would be with that box type thing on top of the car as seen with the union pacific power car 2066 that has one side with doors and the other is just windows 1st Style of OBS Cars: The other power car: has large vents on the side but no box on the top 2. Business Observation Cars An observation car/carriage/coach (in US English, often abbreviated to simply observation or obs) is a type of railroad passenger car, generally operated in a passenger train as the rearmost carriage, with windows or a platform on the rear of the car for passengers' viewing pleasure. 2 Forms of observation cars for this pack: 1st Style of OBS Cars: 2nd Style of Obs: (has more lights) 3. Inspection Observation Cars: These cars featured theater-type seating, which faces a large rear picture window to permit unrestricted viewing of the track and structures along the right of way 3 Forms of inspection cars for this pack: 1st Style of inspection cars (has a large dome on the top of it): 2nd Style of inspection cars is like a large double decker type car: 3rd Style of inspection cars is single level type car: This is about all the cars I can think of at the moment, and would easily be $15 dollars. Please do suggest any cars that would fit this pack and it could easily be just one railroad like BNSF and 3rd part skinners could reskin them to be UP, CSX, NS, etc
