Thanks for the link Sebastien

The discussion was so informative that I had to update my copy of O'Berry's "Mudhens"!

Hi guys,

Last autumn I started a thread on the NGDF forum about the K27 valve conversions.
Very good informations were given, by Earl Knoob for example (costs, dates, etc...). The discussion also revealed the only known picture of a K27 in the intermediate state of the conversion : 456 with inboard piston valves and still with stephenson valve motion.

Hey all,

I was wondering if anyone here knows about or could point me towards information covering the evolution of the K-27s.  I'm specifically interested in when their slide valves and Stephenson valve gear were replaced with cylinder valves and Walschaerts valve gear.  I know they were done at different times as the engines were shopped.  I'm looking at what time frame that occurred like 19xx-19xx.

Thanks,

450, 451 and 457 along with 460 were never converted to piston valves and Walschaerts Valve Gear.  They were converted to single expansion slide valves around 1908 retaining their Stephenson Valve Gear.  In the latter 1930's they were seen parted out on the Alamosa deadline.  460 was the last one in service.  462 got its running gear overhaul completed, but the boiler was never superheated.  As it was the last one through the shop in 1930 (a few years after the previous conversions), one could assume the running gear work was completed, the project was stopped and the unmodified boiler placed back on the running gear.

I believe the 460 was the only K-27 that was never converted to walschaerts valve gear. The 462 had no super heater. After contuous shopping, no two K-27's wound up having the same arrangement of parts.

Re: Evolution of the K-27

Earl Knoob
 

In a nutshell:

454, 456, 458, 461 received piston valve conversions in the late 1910's retaining Stephenson Valve Gear and saturated steam.  To connect with the existing valve gear, the valve chests are inboard of the cylinder centerlines.
452, 453, 455, 459, 463, 464 converted to superheat, piston valves, Walscheart Valve Gear 1925-26.
454, 456, 458, 461 converted to Walscheart Gear and superheated at same time frame.
462 converted to piston valves and Walschaert Valve Gear, but not superheated in 1930.
450, 451, 457, 460 were never converted and remained slide valve saturated steam.  All were out of service by mid-1930's except 460 which stayed active until 1938-9.

Re: Evolution of the K-27

So is it safe to say that by the late 1920s most of the fleet had been converted to cylinder pistons and Walschaerts valve gear?  The reason I'm asking is that I'm thinking of changing the period of the RGS I'm modeling from 1940 to the late 1920s.  The K-27s I have all have cylinder pistons and Walschaerts valve gear (and to be honest I'm not all that crazy about the slide valve versions).

Thanks for the information and I'll look into picking up one of the books,
Scott

You will find it was done over a period of time and gradually as the locomotives were shopped over a period of several years

Re: Decoder in C-16

Robert Herrick
 

Thank you, Steve. Wayne offers the kit with no decoder or a mounted TCS back EMF decoder. He doesn't say, but I assumed I'd have to add a separate sound-only decoder speaker, harness, etc. If that's the case, and since I want sound, seems more practical to order the non-decoder and use the savings to buy one. Made a note of your phone number. Will let you know how I proceed. Thanks again.

Hi Bob, correct, I did my own wiring etc. Wayne can do it as well and I believe he uses TCS decoders. I work on my club’s decoders and sound and always use Soundtraxx because I attended the Academy a few years ago and feel very comfortable with their products. That said,you see that i installed a TCS WOW Sound decoder in one of the C-16’s and it is perhaps my best running lokie. Both are great companies and you may even opt for another, but you will have plenty of room in the C-16 tender for electronics. Wayne’s upgrade kit is phenomenal as well... Good luck.
