Unfortunately as the cylinders are hot when a loco comes to a rest the oil within the cylinders is thin and soon runs to the bottom of the bores, as soon as the regulator is opened the majority of the oil that should be protecting the cylinders gets blown straight out of the taps. It's something I witness often, a loco has just run round its train and coupled up, cylinders will stay plenty hot enough for condensation not to form in the 10-15 minutes before departure yet many open the taps and pull away for the first few revolutions of the wheels with them open thus losing that precious oil you are depending on to give long piston, ring and bore life.

There should be no need to close the vacuum ejector before applying the brake to stop. This should remain open. If not, it means one can't regulate the brake to stop precisely and smoothly.

We had a long debate over what was the most realistic way for it to brake, and in fact althought he various systems are well known, its rather hard to tie down what 56xx had for the majority of its working life. There seem to have been some mods to mixed traffic and shunting locomotives which may or may not be applicable in this case. Any mistakes on this are my fault because I help set it up to perform like the Manor in MSTS, which is how most people suggest thats closest to how vacuum brakes perform. I gather there is some modification being done to how it was setup, so it may be rather more realistic than that, we shall have to see. From what ive read it sounds promising.

Suffice to say with the version I played, you could apply brake with the ejector on or off. Its just when its on, you lack

Thanks for the info. As you might imagine, with the ejector (& vacuum pump if fitted) running, the loco will be creating a vacuum and releasing the brake as soon as the handle is placed in the release position. As it is applied, it passes a "lap" position whereby the application can be held. Hope this helps!

much middle point between brakes on and off. So if you want the brakes to stick, shutting the ejector is the easy option.

As I say, that was the version I roadtested. Its probably improved on now.

If its not fixed (and thats arguably my fault if it is not) Ill try and work out how to making a bigger intermediate point, and post up a fix on the forum. In actual fact I think its something you might be able to fix in RW tools in a couple of minutes.

I might add, Pete has done all the work on this thing. I just helped him out a bit on the physics, so if its wrong you can all blame me!

Sorry, my previous post got a bit mangled up although youu seem to have gained the main import! Looking forward to this - I'm sure any tweaks will only serve to improve a model that already seems to be raising the bar still further!
