@Stuart posted:Not only tenders swapped around different locomotives, but in some cases the front engines of articulated locomotives were sometime swapped as well. When the Norfolk & Western upgraded their class Y-5 2-8-8-2's to cast bed frames they took the original front engines from the 19 Y-5's and used them under various class Y-3, Y-3a, and Y-4 locomotives. You can tell by the Y-5's larger piston valves and bridge pipe.
Also, they went and swapped the front engines of at least two Class A 2-6-6-4's. Engines 1205 and 1213 swapped front engines which is notable and noticeable because the 1205 was built with multiple bearing crossheads while the 1213 was built with alligator crossheads. As a result the 1205 had alligator crossheads on the front engine and multiple bearing crossheads on the rear engine while the 12013 had multiple bearing crossheads on the front engine and alligator crossheads on the rear engine.

Thanks, Stuart
Here's 1205 showing alligator up front and multiple bearing on the rear engine.
