Does any one know the heights from rail level to the top of the boiler fittings and cabs on the very early Gresley Pacifics when first built and before they were reduced.
Many thanks in advance !!.
Cheers Tony.

Height from rail level to top of chimney 13' 4" reduced to 13' 1" by reducing height of chimney from11" to 8"; dome casings lowered and shorter safety valves fitted; cab roof height 9' 1 1/4" reduced to 8' 7 7/16" with ventilator still projecting above it; plus lower corners of front buffer plate cut away by 6 1/2" deep and 10" long. From Great Northern Locomotive History Part 3b, N Groves, RCTS.
There is also a specific section on pp22-23 of Locomotives of the LNER Part 2A, RCTS, titled conversion of early A1 class to LNER loading gauge.

If you mean the composite loading gauge then the answer is probably no. I was looking into this a couple of years ago and queried the NRM's Search Engine - which did not have any record of it or any copies. If anybody has one it's a rare piece of history.
The Railway Year Book used to publish the principal constituent company loading gauges as small diagrams but the post-Grouping editions merely included the Berne Conference loading gauge for the Continent and the proposed Standard Loading Gauge for Great Britain.
