Active Mallet Steam Locomotives In The US

[kgbw49]

In another thread there was a discussion of active Mallets. I thought perhaps that warranted a single thread listing the current active Mallets in the US for comparison sake. The following data is from several web pages where the data is listed.

Boiler pressure 200 lbs

Driver diameter 44 inches

Tractive effort 24,600 lbs

Thanks.   Any outside USA?   Mexico or Cuba?   World-wide?

Any Beyer-Garretts  (Sp?) using sream twice?

Any Beyer-Garratts  (note sp.) using steam twice?

None that I know of, and the wheel arrangement isn't conducive to compound engines.

There have been at least two designs of Garratt that used multiple cylinders in each engine (the underrated New Zealand locomotives with three cylinders each, and the original Tasmanian double-Atlantics with four) and at least in theory one of the compounding systems (Smith, type-2 Vauclain, Cole, Chapelon, etc.) could be used on them.  But I have never seen any particular plan to do so, and the double-Garratts I have seen or read about were all intended as simples.

Someone with an operational death wish could design a von Borries compound Garratt, perhaps with the electrical adjustment of the Algerian Garratts to keep the two sides balanced.

This railway in Eastern Germany uses Mallet tanks. Cute little guys, aren't they?

The Harz narrow gauge railway has several as does the Fichtelbergbahn. There are others. I've done most of them on excursions from the U.K. about 10 years ago.

I seem to recall something in a recent CT about 2-6-6-2's in Mexico. But these were simple articulateds, not Mallets.

Of course, if I hit the Powerball, this is the Mallet we probably all would want to see restored to operation next.

Norfolk & Western 2156 Y6a 2-8-8-2 - built 1942

Boiler pressure 300 lbs

Driver diameter 57 inches

Tractive effort 126,831 lbs

The Cripple Creek & Victor RR in Colorado has a 2' gauge 0-4-4-0 Mallet....not sure if it's currently running.

A few more of the Mallet we would all like to be restored next (pictures of Y6, Y6a, Y6b):

Cosmetic?  Very likely.

Operational?  Extremely unlikely.

[kgbw49]

Sadly, I have to agree with you, pennytrains.

But they certainly were a grand conveyance!

Okay, so here is a 19-minute video I stumbled upon that has Y6 2-8-8-2 Mallets in operation, preceded by Class J 4-8-4s at speed at the beginning, and followed by Class A 2-6-6-4s at speed and pulling hard, all accompanied by some great music including some fine accordion music that would make Lawrence Welk proud.

Great stuff!  Could do without the counter at the bottom, but Great film!
