For the southeastern high-speed when you do thee scenarios you either get bronze or you usually get a gold but lately I been getting alot of bronze and I have doing and operating the trains correctly for the service trips but the score usually always is low and I can never get a gold and it happens on Gen 8 btw on the ps4. Also I think it's time that the Br 146 gets updated propulsion and brake sounding too and the pis cause the pis looks way off with the lighter green. Majority of the Old trains that we have needs more improvements like new sounds and updated pis to the trains and needs a better brake system to it. Lastly the M3 for lirr needs to be fixed as the marker lights are never on and you have e to go turn them on yourself which waste time and for the M7 we should get a extended map or something because the M7 needs pis to them it just feels empty on the map it does not feel like rush hour in real life with all the trains and we should have some Diesel trains and if you can't get the license to them maybe try for the M9 or something cause it just feels bland.
Old trains are unlikely to get new sounds and physics. When you buy a new dlc with the same train, dtg will update sounds and maybe physics but the old train stays old. The 146 on dra has new sounds and physics which you can use on other routes. For lirr, they aren't able to make it busy cuz of signaling issues and how complicated it is. They still haven't figured it out so any extensions or trains are unlikely to come
