Re: [CBQ] FT Lettering

Bill:

It reads "FT" and "1350" before "16" and "567A."  And the unit number above is 154B, making this the first instance I've seen of an FTA paired with a B of a different number.

Bill --

The 567 engine had been upgraded to the 567A when FT production was resumed in mid-1943 (after being halted the preceding September by the WPA due to a shortage of materials), with the Q receiving its first FTs in December.  The Mechanical Department's FT diagram lists the engine as a 16 567A (see pp. 16-17 in Bulletin No. 4).

The earliest example I could locate of factory-applied side panel lettering (number only) is F2 153 (July 1946).  Subsequent builder's photos (F3s 121, 123; F7 168) also show just the motor number.  The conclusion is that the engine description lettering was an after-market addition applied by the railroad.  The earliest example of an FT with full side-panel lettering (motor number and engine description) is 114A (with second headlight and wagon wheel radio antenna) dated July 18, 1953.

Phil Weibler's side-panel detail photo of Q FTB 115B leaves some question as to the bottom line's lettering; "16" and "567A" are clear enough, but I'm thus far unable to discern the remainder of the bottom line.  

Athearn Genesis included the side panel lettering on their Burlington System graybacks.  Examples: Q F3 135A-B have both the motor number and engine description in one-inch lettering.  FW&D F7A 752D has the motor number only in one-inch lettering (FW&D reporting marks and motor number are located on the sides of the cab), and FW&D F7B 752C has "FW&D" in two-inch lettering centered above "752C" in one-inch lettering.  A comparison of the lettering/number of characters on the CB&Q models corresponds with what can be gleaned from prototype photographs.

Bill,

Thanks for the actual wording. Obviously, the unit has a replacement engine. The original engines, I believe, were 567 or 567A. I think the “A” model may have come out after WWII. The 567 received gradual improvements to correct problems and to improve performance, reliability and horsepower over the years, culminating in the 567D3A in the GP35 model. Amazing that the basic engine was able to be upgraded form 1350 hp all the way to 2500 hp. With the 40 series, the 645 model was introduced. Some of those original FT crankshafts were remanufactured and installed in 40 series models at 3000 hp. You might say that the crankshaft was somewhat over designed originally.
