The LNER Garratt?
A giant, unique LNER engine, whose only crime was being non-standard? This is what the discord server calls 'Hazel-Bait' (its literally been used to describe this exact engine.)
Both the longest and most powerful steam engine to ever run in Britain irl, she was a beautiful locomotive (I love garratts.)
But there is another reason to love this wonderful engine-the LMS Garratts.
See I don't hate or even dislike the LMS, I actually don't have any railways I dislike outside of those working for fascists or something like that. But the LMS is my least favorite of the big four, and as a certified LNER Fangirl, its honestly fun to play at caring about the rivalry (when in reality I would save any LMS engine in a heartbeat.)
Anyway the poor LMS Garratts deserve their own post (hint hint) but the basic idea is the LMS forced Beyer Peacock, the inventor of the garrat type, to use their standardized parts, and it crippled the poor things. They could still (usually) do the job they were built for, but not much else, when Garratts are famously well suited to many roles.
When the LNER and Gresley approached Beyer-Peacock to build the U1, they had the brilliant idea to let the company who had built practically every garratt in the world, design the engine.
The LNER garratt quickly proved why you let the experts do their jobs, and lacked the Achilles heel of her LMS counterparts. She was withdrawn in 1955 when LMS Jr. (BR) found her non-standard, but was quickly claimed by the North Western region for banking on the Marion Incline.
