| Post subject: | DRG K37s |
Happy New Year everyone. I read recently that the K37s used on the Denver & Rio Grande were standard gauge engines converted to narrow gauge maybe in the 1920s somewhere. I believe the #497 on the D&S is K37, right? Anyway, has anyone come across a picture or more of these locomotives pre-conversion to narrow gauge? I'm so used to seeing them ng, it would be interesting to see a photo otherwise. Also, what road used these engines while standard gauge? Who made the conversion, Baldwin? Any info is appreciated. Thanks. Seth |

The K-37's were originally built as C-41 class standard-gauge 2-8-0's. A quick Google search turned up this page of D&RGW steam photos, indexed by locomotive class: http://ghostdepot.com/rg/rolling%20stock/locomotive/drgw1939roster.htm The C-41 class is about halfway down the page. |

FYI, K37 497 was restored by the D&S shops. the 497 was not liked on the Silverton and the Great Locomotive Swap with the C&TS occurred. The 497 is on the C&TS and K36 482 from the C&TS was moved to the D&S. Later on, K37 499 from the D&S was traded to Canyon City for K36 486. K36's onn the D&S are 480, 481, 482, and 486. K37's left on the D&S are 498 and 493. 493 and 498 (without tender) have been for sale for a few years The D&S does not really want them and the C&TS can not afford them and does not need them. C&TS has 492, 494, 495, and 497 in its stable. That makes the 493 and 498 a nice to have but not a got to have. Doug |

The K-37s were built using the boilers, tenders, and other components from C-41 Consolidations in the 1000 number series. The cylinders, frames, and running gear came from Baldwin, they did not use those parts from the Consolidations. |

I couldn't tell from the photos referenced, but I seem to recall seeing a photo shot from the rear that shows the original standard gauge tender riding on the narrow gauge trucks. Indicating that the tenders weren't really cut back to a narrower width. But maybe I have that wrong and am thinking of some other class of locomotives. Les |

Only the trucks were changed, plus a "doghouse" for the head brakeman was added; otherwise, the tenders remained the same. Nathan D. Holmes' website (http://www.drgw.net) has rosters for both the C-41s and the K-37s, including scrapping dates or current location/disposition. |

Doug 497 wasn't too popular on the D&S because it was a rough riding locomotive (as were all K-37s) and it couldn't handle the curves above Rockwood very well, at least not at the same speed as the K-28s and K-36s (even though the track and bridges north of Rockwood had been upgraded and realigned specifically so the K-37s could run through to Silverton; K-37s never went beyond Rockwood when D&RGW still owned the Silverton Branch.). C&TS doesn't want 493 or 498 because both locomotives aren't worth restoring even if it could afford them; the K-37s it already has are in better shape (either 494 or 495 have been mentioned as possible candidates for future restoration). 497 is currently stored serviceable at Chama; it needs new flues and a complete rebuild of its running gear. |

The K37s had identical running gear to the K36s. The main differences were in the cylinder saddle (I think the C41 boiler was larger) and the firebox required a different type of trailing truck. The tender and trucks are from the C41. The axles were machined to allow a gauge of 36" instead of 56.5". It is interesting to look under the tender of a K37 and compare it to a K36. If I recall correctly, a couple of K37 driver sets are under the K36s. I also seem to recall that at one time or another some of the K37s side rods were used on hte K36s. A few years ago, there was a detailed discussion over at NGDF. It was before they had to change the forum's software. As for the comment on 493 and 498, you are absolutely right. Other than getting a few spare parts (i.e. side rods) for the the remaining K37s, the C&TS does not need them. 493 and 498 have had most of their appliances removed by the D&S. I have equated in my mind that the restoration of the 493 would be like Knots Berry Farm reviving 464 in the 1970s - replacing almost everything. The 498 without tender would cost even more. Why 498 ended up without a tender, there was a long thread on NGDF about tracing the K37 tenders and all the swaps in the 1950s and 1960s. Very confusing and interesting and I think it was also on the old software. Doug |

The C-41 boilers and fireboxes were a bit larger than those of the K-36s, so heavier trailing trucks and a different cylinder saddle were needed; otherwise the frames and running gear of both the K-36s and K-37s are the same. Hmmm... I'd thought the tender trucks were the same (except that the wheelsets were regauged) but I wasn't too sure. |

That's all they did, regauge the wheel sets. However unlike Z scale to G scale, Axles have a shoulder on them where the wheel casting is pressed on. This prevents a narrow gauge. To change from SG to NG, the shoulders for the wheels must be moved in to 36" gauge back to back dimension. Thus the need for re-machining the old axles. Doug. |
