Hump shunt !

[whittaker]

Quick question
I am busy putting some alterations to the Newcastle route and intend to add the hump shunt to tyne yard .

The question is will the wagons coast enough to make this work.

Adam suggested on the official forums that hump shunting is not yet supported in Rail Simulator.

just tried it on my Washwood Heath hump shunt. While the loco will run down the grade when pushed and uncoupled the wagons travelled about 3 metres before stopping

might have a bit experiment with gradiants and wagons

worth a try

From what Ive read part of the problem is that the wagons have a setting in the file that sets the handbrake, if that is set to zero then the wagon will roll more ( I not exactly sure about the details though ).

I got a US boxcar to roll one full car length after uncoupling on a six percent grade. I'm thinking about pushing it over a cliff, but I suspect the little beastie has a parachute. :bad-words:

Knock the handbrakes to zero in the bin file, load em up and watch them roll...

Loaded wagons roll a lot further, and the wagons will not roll away on their own on a 1:50 grade

This was tried prePatch and with the 16T Mineral... other stock may have issues with automatic brakes

Thanks for that sly410

have a try of that

I think we need to distinguish between
a) a potential bug in KRS which causes the handbrakes to come on once the wagon is uncoupled. For handbrakes, this is certainly wrong. By the same token, you could demand that the automatic brake would come on when you uncouple. You would need a separate option in the coupling window "close brake valves" -- if you do that before uncoupling, wagons will coast, otherwise, they will come to an emergency halt. At the same time, if you couple but do not click the same icon again, meaning "connect hoses" now, you could shunt the wagons without being connected to the automatic brake of the engine. But I'm afraid, I started to dream about realistic train simulation again ...

b) quite insane figures for handbrake force. The example in the docu mentions 2500kN. This is what I would use for a 2500t vehicle. With a little experimentation, you might be able to find a value which make your wagons run down the hump but stop somewhere in the track following -- you do not want to have them run away. I would start at 10% of the wagon mass, i.e., for a 40t wagon, I would start at 4kN, and probably increase that a bit, but I am really not sure, it depends on the shape of the hump and the length of the track beyond it.

I think i will start by altering the value on the 16t mineral wagon .

most of the wagons used over the shunt at tyne yard were unfitted ,if not all!

i will post the results after i have messed on a bit.
