A footnote to the chime whistles; 4492 /60013 'Dominion of New Zealand' was fitted with a very different toned one from a New Zealand Government Railways 'Ka' class. Sadly, this loco was not taken up on offer for display here. Nor 4491 / 60012 'Commonwealth of Australia'.
THE U BOAT ENGINE - AND THE A4 ! Indeed the "interest" in the German "Flying Hamburger", was NOT confined to a purely Railway Interest ! The Interest extended to organisations including MI5. The suspicion was of course that the "Flying Hamburger" and its "offspring" was a clever way to secretly test "U Boat" engines. Forbidden under the terms of the Versailles Treaty of WW1. So Sir Nigel Gresley's trip to Germany, which included a team of Railway Engineers, two of whom were actually Naval Engineers ! The modern counterpart to this is the British Rail HST, which used the Paxman Valenta engine, designed primarily for use in Fast off shore Coast Guard type vessels !! The engineering behind small ship or submarine engine testing. Is that if the design can survive the brutal environment of a railway train, where the constant vibration and bumping & swaying over track, seriously rattles a diesel engine about. The design should have no problem with gently wallowing around on the Ocean. The HST proves the point.
Superb, thanks for posting this.

Mallard and the A4s . . . . you inserted the apostrophe - why ?
An ordinary thing about apostrophe, using it where it isn't needed and omitting it where it should be.
Mallard is a pretty girl
