Class 4 Tank Locomotive

I have dug up some interesting information about the Class 4 Standard Tank locomotive like the one in the EDG18 train set:

Driving Wheel: diameter 5ft 8in (6ft 9in for a Coronation Class)
Pony and Trailing Wheels: diameter 3ft
Length: 44ft 9 7/8in
Weight: 86 tons 13 cwt (that's about half the weight of a Duchess)
Water Capacity: 2,000gals
Cylinders: 18in x 28in
Boiler Pressure: 225lb sq in
Tractive Effort: 25,100lb compared to about 40,000lb for the Coronation Class (Duchesses of Atholl and Montrose for instance)
Coal Capacity: 3.5 tons



Rail transport is still about the most efficient means of transporting large volume goods and passengers available to humans with the exception of teleporting.

Some meaningless figures just stolen from Wikipedia - the font of utterly useless information:

Kj Energy Used per Tonne-kilometer
Class 1 Railroads 246
Domestic Waterbourne 370
Heavy Trucks 2,426
Air freight (approx) 6,900

Take the train - You know it makes sense!
