Curious choice of shunters wagon though. It suggests that the damage to the structure isn’t too bad if they are prepared to hang other locos off the tender.

It is in steam, you can see steam coming from the whistles. It's not a lot of fuss about nothing, it's gone 25' through a set of closed shutters that could've had people working behind it.

I really feel like this discussion is trying to argue black is white, but I think it summarises to this: 1. Compounding in the UK context never made any business sense at the time. 2. You could build a 2 cylinder compound engine, but it comes...

So it isn't the same mass. The temperature and pressure might be lower but the pressure is acting on a larger piston area, so the piston thrust, if the designer has proportioned the cylinders properly, should be about the same. There isn't...

21B liked jnc's post in the thread North Yorkshire Moors Railway General Discussion.
People like to blame her, but I think a really large share properly goes to the people above her (who have done more incorrect than just hire her). Not that she isn't making even more mistakes, of her own, of course, but a lot of what she's doing...
