I like Submarines&Trainz
i was looking around in a book store for a giant train encyclopedia for creating a couple of trains in them for reference. right after i went past prr's s1(6-4-4-6) i came upon the challenger. it said that np had two. is this true along with clinchfield, cnw, d&rgw, up, and wp? cause thats what it said. it also had something about the huge boy (4-8-8-8-4).
 
NP had more than two challengers, but not many. CNW never had one. But Clinchfield, UP, WP, D&RGW, and NP all had challengers.

Also, there is no such thing as a "Huge Boy"...while similar wheel arrangements were tested and ultimately proved unreliable by the Erie and the Virginia, and it's possible that a 4-8-8-8-4 may have been in preliminary, no "Huge Boys" have ever been manufactured.

Howdy...There is a Huge boy available as Payware from TRAINZITALIA's West From Denver website. Nice to dream.:wave:
 
NP operated 47 Challengers in classes Z-6, Z-7, and Z-8. SP&S operated 8 Challengers based on this same design. Great Northern owned none, but leased, operated, or whatever a pair of SP&S engines since GN was half owner.

Clinchfield operated 18 Challengers in three classes. Six, the E-3 class, came from D&RGW, having been rejected after WWII ended as they were built to UP's plans and not D&RGW's. D&RGW operated 15 of their own design.

Western Maryland operated 12 Challengers in their M-2 class (the M-1's were 2-6-6-2's converted to 0-6-6-0's for heavy yard work). WM found out the hard way that they were really high speed freight engines and not drag engines. Trains Magazine ran a nice article on them in April 1992 or so by Bert Pennypacker IIRC. (WM probably would have been better off with 2-8-8-4's.) Along with the D&RGW engines, these were the only Challengers built by Baldwin. All other were built by Alco.

Delaware & Hudson operated 40 J-class Challengers. Most sources claim that they were the prototypes for the engines operated by CRR, WM, D&RGW, and WP.

UP operated 105 Challengers, and WP operated the smallest fleet - only 7.
