Comment 6 for bug 1391449

Hi Dennis,As I reported this as a bug concerning locos which required the use of the Small Injector to release the brakes, my first test only used such locos.As such, this is my initial report.I used the Bala Hub route because it has a good selection of GWR/exGWR locos - I know it's not on your list! I tested using MSTS, ORTS X2647 and X2649. Of the 15 lsuitable locos in this route, 9 used the Small Injector.The average time between pressing the <;> key and the loco beginning to move :MSTS : 10 seconds (Small Injector already opened) (ranged between 9.0 and 11.9 seconds)X2647 : 42.5 seconds (ranged between 33.0 and 48.6 seconds)X2649 : 5.0 seconds (ranged between 3.5 and 6.0 seconds, although the 3.5 loco was an outstanding exception!)
For my next report, I'll select GWR/exGWR locos from other sources. I'll also include some other vacuum-braked locos to test their performance.
Well done for this effort!! Although it might now be too quick for the purists!
Regards,Ged

> Bug description:
> Hi,
> In accordance with real-life practice, many MSTS models of steam locos with a Great Western Railway origin require the Small Injector to be open in order to release the brakes. This is not, currently, included within Open Rails with the result that it not possible to satisfactorily drive these locos. I say "satisfactorily" because after a comparatively long time (2 minutes), the brakes do release. This is shown at the top left of the OR screen against the Train brake entry where, when the value of inHg reaches 19, the loco starts to move (the maximum for this value is 25, which was the standard pressure for GWR locos). Typically, MSTS takes just over 1 second to release the brakes once the Small Injector is opened. When running in MSTS, the Small Injector is closed to conserve steam; the brakes can be applied normally when it is closed.
