ATSF Guy; CGW121:
Alternative facts. Dimensionally almost identical. Details differed. Look it up.
T&P 2-10-4 655-59 built by Lima in 1929: 28x30 cyl.; 63" dri., 255# b.p.; 100 s.f. grate area; 98,500# t.e.; 307,000# wt. on dri.; 457,500# tot. eng. wt.; 3.63 F. of. A. (other T&P 2-10-4 orders differed slightly)
CGW 2-10-4 850-864 built by Lima in 1930: 29x32 cyl.; 63’ dri.; 255# b.p.; 100 s.f. grate area; 97,900# t.e.; 304,000# wt. on dri.; 461,000# tot. eng. wt.; 3.59 F. of A.
Compare these with the Santa Fe 2-10-4’s:
Number 5000 built by Baldwin 1930: 30x34 cyl.; 69" dri.; 300# b.p.; 121.5 s.f. grate area; 93,000# t.e.; 372,000# wt. on dri.; 502,600# tot. eng. wt.; 4.0 F of A.
5001 Class built by Baldwin 1937: 30x34 cyl.; 74" dri.; 310# b.p.; 121.5 s.f. grate area; 93000# t.e.; 371,680# wt. on dri.; 545,260# tot. eng. wt.; 4.0 F of A.
5011 Class built by Baldwin 1944: 30x34 cyl.; 74" dri.; 310# b.p.; 121.5 s.f. grate area; 93,000# t.e.; 380,300# wt. on dri.; 538,000# tot. eng. wt.; 4.09 F of A.
Like it or not, the CGW was not a big road with a sufficient following to justify tooling for a big consumer demand. That’s reality. But if you really want a CGW 2-10-4, it’s possible to get one with the T&P as a starting point. If the project isn’t sufficiently important to you to justify the effort, you’ll have to do without. Dr. Wayne and Casey have proven that it’s possible. If you prefer to base your model conversion on the much larger Santa Fe engine, and think you can pull it off, you can start with a Bachmann. Your choice.
