Farish already released retooled class 90 and LNER V2, GWR Hall, so I think they will release it someday

In post #315, John showed hid excellent model of cylinders and valve gear arrangement.

On a recent holiday, we visited the Amberley museum. In the railway hall/exhibition  shed, there is this model of 'how valve gear works'. It may help understand the process. The 'valve' is slide type, not unknown but unusual for Walschaerts valve gear. The gear can be operated to show the workings.










On at least some railways, a withdrawn loco would have had its boiler removed but retained the valve gear; this was then towed to the loco sheds so that staff could see how the gear worked, and practice how to cure faults or dismantle it as a 'First aid' measure to get to the nearest station.

I think if you magnify the photo, you can read the explanation of how this type of valve gear worked.

Incidentally, if you wish to visit the museum, it is only a few yards from the (still open) main line railway station, across the former goods yard and private siding.

Sorry for late response. It seems I'm not getting emails or notifications anymore. Checked my settings and nothing changed, so I just clicked save anyway in hopes.

But man, Dee Snyder got old. Still sounds good though.

if you dont want electro magnets try making the loop out of the steel wire supplied and get a small strong magnet on a coffee stirrer and with a bit of practice this works. you can read about it on RMWeb 2mm section in on of the projects by izzy, I think they are priory road , Tendring or Circle sidings possibly

I agree with PLD about the magnets; Peco too weak, PK very good (but remember, they need a switch, I think, which is not included), EM1 very good and come complete with switch.

I'm interested what make and how much please

Quote from: martyn on Yesterday at 11:39:20 AMI might need a few!

I've got a few as well, that I got from Dave then changed my mind - ended up using servos to move magnets under the baseboard.

Quote from: Will_J on Yesterday at 10:08:31 AMI've never used it but Peco made an electromagnet for uncoupling, code PL-25. Might be what you need.

Using B&Bs which operate on the same principle as DGs, I've found the PECO electromagnets to be weak. My preference was the same PK magnets from Wizard, with SEEP (now Gaugemaster) EM-1 as the next best.
