Great topic! Of my 15 locos, all are MTH Premier steam except one rectifier electric. of the larger ones I have, I have to say that the Erie Triplex is the most impressive even if it was never really put to the test because it used too much water and had more torque than the couplers of the day could handle. Others in my collection include:
Baldwin 4-6-6-2 M2 Challenger and the 0-8-8-0 Camelback (Would hate to be an engineer on that one!).
But the ones that I can spend hours watching, although they are not truly articulated are the Shays. That row of steam cylinders and the crankshaft churning away and driving all three trucks with a dozen or more log cars going up a steep grade is an engineer's dream.
Would love to get a Cab Forward though as it is so unique. I always wondered why there weren't more cab forward designs built as soon as oil fired boilers were available.
And maybe I will even get some track up (ceiling layout) to run them on this spring!
