The UK's Second Oldest Surviving Diesel-Hydraulic Locomotive Named Triton Number 1932 on The SNBR

Scarborough North Bay Railway number 1932 "Triton" was constructed in 1932 by the famous locomotive builders Hudswell, Clarke & Co of Leeds. This historic 20-inch (508 mm) gauge miniature asset is a steam-outline diesel-hydraulic locomotive featuring a classic 4-6-2 "Pacific" wheel arrangement, designed to replicate the majestic appearance of a mainline LNER express steam locomotive. Built at the absolute dawn of internal combustion rail traction, this locomotive represents a genuinely pioneering chapter in global railway history. Rather than utilizing a traditional manual gearbox, it was equipped with an incredibly advanced Vickers-Coates torque converter fluid transmission to pioneer smooth, gearless acceleration. Alongside its 1931-built sister engine Neptune (which debuted this technology), Triton stands today as one of the oldest surviving operational diesel locomotives in the United Kingdom and one of the absolute oldest surviving operational diesel-hydraulic locomotives in the world, serving as a priceless living milestone of early fluid-drive engineering. It remains beautifully turned out in its traditional LNER Apple Green livery.

The locomotive is seen here in 8K 16:9 widescreen executing a smooth arrival at Peasholm Station, proudly carrying a vintage "The Scarborough Flier" headboard on its smokebox. Hauling a beautifully uniform rake of five passenger coaches, the iconic miniature pioneer glides into the platform to complete its scenic coastal journey along the North Bay on Wednesday 01/07/2026 at 13:49.
