MellishR 支持 35B 在 GWR four-cylinder arrangement? 内发表的帖子.
Yes, one-offs. In comparison to what was coming out of GE and GM, the N&W steam types were relatively few in number, and lacked the economies of scale that the diesels provided. Taking your list of Y6, A and J classes, that was a total of 138...

MellishR 支持 LMS2968 在 GWR four-cylinder arrangement? 内发表的帖子.
Yes it can, but there are still limits as to the power which can be generated and then delivered; diesels (and electrics) do not have super powers when it comes to climbing gradients. There are still limits. There are advantages and...

MellishR 支持 ghost 在 New build M&GN C class 内发表的帖子.
Neither project would be mentioned here as this is a thread for a specific standard gauge loco. Gowrie is mentioned in several of the FR threads. The ZA6 has its own thread which was updated in March 2026. If you have updates, feel free to...

MellishR 回复主题: GWR four-cylinder arrangement?.
Thank you for the point about traction current. In effect that limits the tractive effort at low speeds, if the adhesion limit isn't reached first. But can diesel not produce a more nearly constant power at the rail than a steam loco over a range...

MellishR 支持 Steve 在 GWR four-cylinder arrangement? 内发表的帖子.
What’s wrong with the first post? Within the limitation of adhesion, a diesel locomotive is a constant horsepower machine whereas a steam locomotive is a constant tractive effort machine within the limitations of its boiler.

MellishR 支持 Jamessquared 在 Flying Scotsman 内发表的帖子.
It’s interesting looking at dates and times that the Stourbridge - Bristol and Bristol - Minehead trips look like they are essentially a single combined day out for the loco and carriages, but two separate sets of passengers. That’s clever, it...

As a comment there was generally less electrical signalling equipment trackside 60 years ago. Cheers, Neil

A classic example in this photograph of the perils of not clearing lineside vegetation. The metal cabinet didn't catch fire, it was obviously surrounded by vegetation that did and the contents of the cabinet were effectively "cooked". I am old...
