Hello. I hav been playing morristown and Trenton lately but have noticed that when performing a hill start the train will always roll backwards. This isn't such an issue in the ALP 45 AND ALP 46 as they have an independent brake but the multi level can car doesn't. The procedure I am following is afaik correct, setting the lap brake to hold, applying power then releasing the lap brake. The brakes bleed off and the power comes on but not quick enough to prevent a roll back. Is there anything I am missing? I really want to like this route and another one is coming but if it's going to do the same thing I won't bother with it. Thanks for any help. Liam
Have you considered applying more brales before moving? I find that the trains brakes take a longer time to release from something like 60psi instead of 90psi which might give the locomotive more time to apply power before the brakes are fully released.
You can only add power when they are in hold not before and power won't start until the brakes release and so it won't make any difference
That's not what aeronautic237 means, I think. If you apply more brake, it take longer for them to go off. So set the train to full brake, when you're ready to depart, switch the brake off and apply power. As it take longer for the brakes to come off and you give already power, it's less likely you will roll backwards. I do not know this paticular train, but if those train brakes are like aeronautic237 discribed, then it should work.
It makes no difference they will take longer to release of course but the fact remains power is still prohibited to apply until the same point releasing from suppression. It's bad physics apparently. I would file a ticket if I thought it would do anything but I have filed them before, been thanked for my 'keen eye" and the issue never fixed.
Is see what he means now bypass the hold detent, release from full afaik not the proper way but it did help.
Yes like that, I don't know how they do it irl with those trains. But it seems applying power goes not quick enough after releasing the brakes from hold.
On a 1.1 gradient full brakes applied and power added upon release it will still roll backwards a little there's nothing else I can do
To prevent roll back, put the train brake into hold, apply power and bail the independent brake. Don't release the train brakes until you see the amps build up or you hear the propulsion kicking in.
Thank you lexie for clarifying what I meant. I have a tendency to word things poorly. I tested it on that really steep bit of hill in the training centre and I also rolled back (but I believe it was a 1.8% gradient). Power is only applied once the brake cylinders are released. I've been experimenting with the brake cut-out and cut-in switches, and while the train still rolls back on the really steep hill, it can help bring power on slightly earlier. I'll reply with a video shortly.
Alright - you get mixed results but it's the best I could find. BP = Brake Pipe ER = Equalising Reservoir psi = Pounds per Square Inch (the unit of pressure used in the gauges of the cab car. 1) After you stop, release the brakes and be ready to cut-out the brakes. 2) Once the BP reaches 90psi, cut out. 3) Once the ER reaches 70psi, cut-in. 4) Repeat steps 2 and 3 until the BC reaches 0psi (should take between 3 - 5 repeats but I like to add one more for good measure). 5) Cut-out the brakes again once the BP reaches 90psi. 6) Once the ER reaches 45psi, cut in the brakes and apply full power immediately. 45psi is exactly halfway between 40 and 50psi on the gauge. 7) You'll roll back a bit, but then the hill start is complete and you can reduce power if you wish. As you can see, this takes a bit of time so you might want to start the procedure WHILE the doors are closing (instead of after they have closed) in order to keep to schedule. I also have no idea why the train doesn't roll back when the brakes are cut out but the cylinders are at 0psi. I've also just realised you're on an Xbox so none of this is helpful to you since you haven't got a mouse. I'm sorry and I hope it helps any PC players out there. In the video, I've kept the HUD up so it's clear what the train is doing but I was using the in-cab dials to get the pressures.
