4 Truck Shay

Recently got another 3 truck B’mann shay and have always admired 4 truck shays. Has any one ever considered, or actually, converted a B’mann 3 truck shay to a 4 truck shay? Any problems encountered in the conversion?

Nooooooooo! Noooooooooooooooo!

I’m calling the The-Last-Thing-I-Need-Is-Another-Shay police!

Ahhh yeas…a $ truck Shay. When I built mine the three trck Shay hadn’t come out yet, so the biggest problem was sourcing two rear facing sliding shafts with universals. At the time you had to get those off broken crankshafts. The Engine driveline and trucksa are really all I used, I scratchbuilt the frame and everything above that. I can prolly dig up some pics if anyone is terribly interested…

I’m interested …

I had never seen a 4 truck Shay until now. Are there any 1:1 Shays like this still in existence?

From Wiki:

In 1903, Lima could claim that it had delivered the “heaviest locomotive on drivers in the world”, the first 4-truck (class D) Shay, weighing 140 short tons (120 long tons; 130 t). This was built for the El Paso Rock Island Line from Alamogordo, New Mexico to Cox Canyon, 31 miles (50 km) away over winding curves and grades of up to 6 %. The use of a two-truck tender was necessary because the poor water quality along the line meant that the locomotive had to carry enough water for a round trip.

Classes

Approximately 2770 Shay locomotives were built by Lima in four classes, from 6 to 160 tons between 1878 and 1945.

  • Class A: two cylinders, two trucks. Weights between 6 and 24 tons.
  • Class B: three cylinders, two trucks. Weights between 10 and 80 tons.
  • Class C: three cylinders, three trucks. Weights between 40 and 160 tons.
  • Class D: three cylinders, four trucks. Weights of 100 and 150 tons.

Note: Two 15 ton Shays were built with two cylinders and three trucks.

Twenty Class D shays were built. They were no more powerful than Class C, but had greater fuel and water capacity, resulting in improved adhesion.

Four Shays were built left-handed, all special ordered for the Sr. Octaviano B. Cabrera Co., San Luis de la Paz, Mexico.

No mentions of any operational or static 4 truck Shays.

That is just patently weird looking!

I always thought it would be neat to build a Yahs.

Yahs=Shay running in reverse! (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

Joe, or a backward Shay. Or as Dennis says, left handed.

Anybody remember John Allen’s Yahs for his railroad?

As long as we’re on the subject of locomotives with extra trucks…what the heck is this little devil? and I’ll be nobody’s ever modelled it. Can you imagine the radius you need to run it?
