Where the PRR T-? 4-4-4-4 engines articulated?
No, they famously were rigid frame. And they slipped, but there is some controversy on whether that was a "throttle handling" problem or a design flaw.
If GM "killed the electric car", what am I doing standing next to an EV-1, a half a block from the WSOR tracks?
There were a couple of articles on the T-1's in Trains in the late 1960's - 1970's time frame.* The best was a 'sidebar' essay by Vernon L. Smith, I believe, entitled "And the Case for the T-1" as part of a longer article on big american steam locomotives; the other was by Robert A. LeMassena, if I recall correctly. My recollection is that Smith attributed their 'slipperiness' to unequal loading on each engine unit - a design flaw, but I suppose different views of the facts could lead to equally well supported differing conclusions.
