WORLD'S LARGEST O SCALE RAILCAR MODEL???

 

Could this be the largest O scale railcar ever made???  The prototype and the model were built in the USA in 2012.

 

The prototype:

Newly manufactured Schnabel car, WECX 801. It was built by Kasgro in New Castle, PA in 2012 and is the "World's Largest Rail Car". It is owned for Westinghouse and will be primarily used to transport Nuclear Reactor Containment Vessels. The car separates in the center and the load becomes part of the entire car, increasing its already long length. The prototype WECX 801 is a 36 axle railcar that has a load limit of 2,035,800 pounds. The prototype railcar allows for adjusting the load to either side to compensate for overhang on curves. 

 

The scratchbuilt model:

This O scale model railcar has 36 axles with a scale length of 231 feet over the couplers (with no load attached). Two identical sections have been built. The 2 sections are linked together using a drawbar when no load is attached. The O scale model is well balanced with a low center of gravity which allows it to track very well.  This O scale model is over 58 inches in length (without a load attached) making it one of the longest fully operating O scale models ever built. The model as shown is "linked" by a drawbar that connects both sections just like the prototype. With an 80 foot scale load (as shown) it is over 6 feet in length!

WORLD'S LARGEST O SCALE RAILCAR MODEL???

 

The turning radius of the car is NOT the problem. The real problem is the amount of "overhang" for the load.  The prototype car must constantly be readjusted to re-position the load by shifting to the left or right to keep the centerline of the load over the track. If the "load" moves too far off center the car will tip over. The prototype car has hydraulic cylinders which shift the load either left and right or up and down. However there is a limit to the amount of adjustment.

 

 

The "load" attached to the model is a scale 80 feet in length as shown. 

 

Note: The model will easily handle my O-72 curves "without" a load attached. With the load attached it would require O-120 curves or larger. The load is 80 feet long which is about the length of a full length passenger car or an 89 foot flatcar.
