Yes. CORRY RAILS has concluded that A-313 is an 18 Ton 1902 Climax. It was previously known that of the Climaxes which went to Alaska that one (1) was a 18 Ton Climax and the rest were 15 Ton Climaxes. It was only after comparing all the parts of A-313 with catalogs of the period was it concluded that A-313 which was sent to the gold fields at Counsel was an 18 Ton example.

The rear locomotive looks a lot like the 18 Ton A-313 except that the illustrated locomotive has the sheathing on the rear of the Cab on the OUTSIDE of the rear cab framing. I have a photo provied by CORRY R.A.I.L.S from the Estate of Keith Christensen taken before the locomotive was dismantled which clearly shows the rear cab sheathing on the INSIDE of the rear cab framing. That may have changed over the life of the locomotive but it does suggest that the rear locomotive was not A-313.

Also, the Side Rail of A-313 was not uniformly at the same height as on the pictured locomotive.

An interesting device on A-313 used to keep coals hot over night to fire the boiler in the morning with an Ash Dump.

That looks a lot like how some Ikea furniture goes together. Great solution, had no idea it was used on railroad equipment.
