Don't worry Mark, I have found this info on the Class 52 Western's:

"The Western locomotive has two 65 litre Maybach MD 655 diesel engines each driving a Voith hydraulic transmission, which turn the wheels via a gearbox. The cylinders are arranged in a V formation driving a common crankshaft. The Maybach diesel engine has 12 cylinders and produces 1380 hp at 1,500 rpm. Maybach diesel engines were also used in marine installations such as motor torpedo boats and fishing boats."

2000bhp at the wheels.....when they work.

6 valves per cylinder

crank journals are so big crank can be slid out. Bearings are huge

The 52s come off power at quite a low speed compared to the large EE devices, so at high speed the best type 4 was the 50.

However the 52 is sure footed, but does have a hole in its power going from 1st to 2nd

Interesting  Martin, and they certainly sounded good when I was a child, with them hauling the Torbay Express that I was on once, along with Warships that did the same in the early 1960s.

I did miss the Halls and Castles though when these 'boxes on wheels' came along
