The new locomotives were substantially lighter than previous diesel-electric designs: a Class 44 "Peak" locomotive weighed 138 tons and required 8 axles to carry it; the D800s weighed less than 80 tons and only needed 4 axles
I don't think this is quite a fair (or correct comparison), comparing a design of similar age Class 20 shows basically comparible axle weight, engine power, and tractive effort (the class 20 is ~10% less in most respects , as well as being slower)...
The class44 comparison would always be a bad one since it is an awfully heavy loco...
Suggest comaring to a non-elephantine loco. Thanks. (tend to agree all the same with the principle though.) —Preceding unsigned comment added by 87.102.85.58 ( talk) 23:34, 10 January 2009 (UTC)
The theoretical advantage of diesel-hydraulic was simple—it resulted in a lighter locomotive than equivalent diesel-electric transmission.
Are you sure that 870 wasn't refitted for multiple working too? I lived in the North, and my first ever (hence memorable) sight of Warships was at Temple Meads on a family holiday to Devon in (i think) 1968. Our Newton-le-Willows to Newton Abbot motorail stopped on a centre road side-on to Magpie and Zulu. I suppose there could have been a second driver on board Zulu, but that would be odd. Happy days. 86.148.252.237 ( talk) 18:31, 26 August 2010 (UTC)

1. I changed the text to give the max speed ot the West German V 200 as 140 km per hour, as opposed to the incorrect 120 km per hour previously stated in the text. -- Look up the wikipedia-texts about the West German V 200 which correctly give their max speed as 140 km per hour.
2. West Germany did NOT have a 120 km per hour speed limit at the time mentioned in the text.
3. This was East Germany where speeds were that restricted.
4. East Germany did have a type they called V 200. That was totally different from the West German V 200.
In fact, the East German V 200 was of the Soviet M 62 type utilized across the whole Eastern bloc railway sytems. Its max speed was only 100 km per hour and it was almost exclusively used for goods trains, due to a lack of train heating equipment.
