It hadn't dawned on me until now really. But all your F-Units are coded for a 26C brake vavle, but proto-typically have modeled a 24RL. Any reason there is no coding for a 24RL besides ease for beginners? Also, and this doesn't just go for your F-Units, but pretty much all MSTS Payware, but why are the dynamic brakes coded to have essentially, notches? I don't think i have ever seen or operated dynamics that have notches on any piece of equipment, I imagine in real life it would create some SERIOUS train handling issues.
All this is easy for me to change in the sim, just a couple curiosities.
