Power Outage

Post by Movingmillion on Mon Aug 13, 2018 2:38 pm

As part of one the 2011 scenarios, we will have a route that ends at Northwood, and putting the train into the scrap siding. I am aware that the train then rolls to the end of the sidings, without any power. Is there a way to replicate this on openBVE, or will concessions have to be made?

If a train is on a gradient and the brakes are released it will roll in whichever direction is downhill.
The physics is already there, all you need to know are the train weight and the gradient to set up the train.dat file and the route file.

No need for extra gradients which don't exist in reality. Either it accelerated from a section with power, left it and stopped in the scrap siding (since it was still rolling because of inertia), or there was a slight slope already.
Any videos of the actual process?

There are some on YouTube, but for the life of me out of my adoration of the A Stock I genuinely cannot bear to watch it.

I think we have a slight misunderstanding here. What Movingmillion wants to achieve is for the train to have no power on a part of the track. It is achievable via plugin. You'd have beacons signalling "power on" and "power off".

Is it possible to give the conductor rails some of these properties? Where if the train shoe goes off the rail for  a certain period that the motor cuts out? And also, can you give an example line of code of the commands we would need to use to cut the power from the certain block of track?

I remember it's either about beacons placed exactly where the power rail start and end, or a beacon placed at the end with the gap length specified through it. Look it up in BVEC_ATS documentation, it has similar to Os_Ats functionality (which most LU trains use) but works better with OpenBVE.

One beacon should be placed at the start of the neutral section in this format:
.Beacon 20;x;0;Length
x represents the structure index of the beacon to be displayed.
Length represents the length of the neutral section from this point in meters. This number must be positive.

OS_ATS and BVEC_ATS support this, but must be set to electric traction, and the power pickup points / behaviour set appropriately.
Haven't looked into the config of the LU trains, but if you let me know the one you're playing with I can take a dive.
