Heres a gameplay tip for those of you currently playing on Lirr. When it comes to using the door override key, just move the cursor a bit to the right or left of the keyhole to take it out. The end of the key is used for turning. Also you can leave the key in to keep the doors activated until you're finished the service. Its optional. I preferably only take the key in and out of the doors to the left of the engineers panel because not many stations serve that side when in transit. It's more realistic that way. Another tip is if you happen to receive a penalty brake, or accidentally trigger the emergency brakes, you only need to reset the throttle to full service brake (Max Brake) and then charge the cylinder back to 90 psi which you will be allowed to continue moving in no time. No need to set the reverser to neutral and no need to wait a minute or 2.
