That myth came back to haunt me this evening when re-reading Cecil J.Allen's British Pacific Locomotives, a favourite volume of mine. For on page 109, under the heading "A1 Class" and referring to a set of trials in 1949, it reads:
Left slightly speechless reading that - exactly as described by my grandfather. The question is - given I have never seen this information crop up anywhere else - how much truth is there in this, and did 60114 work with a single chimney at any time, and is there a photograph of it so equipped?The tests just mentioned took place in 1949, and were made in order that the performance of the 'A1' and 'A2' might be compared with that of the Gresley 'A4s' in the historic exchange trials of the previous year between locomotives of the various regions of British Railways.
The Peppercorn engines selected were No.60114 W.P. Allen of the 'A1' type, and No.60539 Bronzino of type 'A2'; whereas the latter was the only 'A2' which started its career with a double blastpipe and chimney, the former at first had been built at Doncaster with a single blastpipe only, though in common with all the 'A1s' it acquired a double blastpipe later.
