M-2c Class Details

[NW Mailing List]

Thanks, Ed.
I have seen mention of the Hobart-Allfree cylinders before but I don't know what they are or if they have distinguishing features I can spot. Some M & M-2 engines (as well as Pacifics) have the steam pipes on the outside and some not visible on the top of the cylinders. Is that what you are talking about?

I have a PSC HO M-2c that is factory painted as 1157. It has unported cylinders, single stoker engine, BL heater and with a 9A tender. I guess it's modeled after how it looked early on as it has the high N&W number board type headlight and road pilot.
The Sunset models all have the ported cylinders, single stoker engines, BL heaters, high Pyle headlights, footboard pilots and 12A tenders.
Most photos I have found of the 1151-1160 engines show the ported cylinders but most all are engineer side views so I don't know about the BL heaters. 

Naturally, details come and go over the years as I have some pictures of engines with and without the ported cylinders or BLs and most have tenders, pilots and headlight styles & locations changed throughout the years.
Many thanks for answering my questions.

Roger -  The M-2 engines with the Walschaerts valve gear werethe fifty original Baldwins of 1910 numbered 1100-1149.  Roanoke builteleven more numbered 1150-1160 variously classed as M-2a, M-2b and M-2c. These engines all had Baker Valve Gear and the subclasses had eitherHobart-Allfree cylinders (M-2a) and/or stokers and/or superheaters. Eventually they were all changed to the M-2c standard of stokers andsuperheaters, the Hobart-Allfree experiment also seen on the E-2b Pacifics wasgiven up.  There is a photo of the left side of 1157 in the book on theN&W class A and there were several photos of the 1100s in the Thieme picturebook.  All the M-2s were eventually equipped with superheaters andstokers.  I don’t know if all the M-2s got feedwater heaters.  Thebulge on the side of the cylinders was a form of drifting relief valve. The single cylinder stoker engine was for a Duplex stoker; most of those weretaken off in favor of the Standard stokers with the two cylinders; the 1157 isso equipped. Hope this helps.

Can someone enlighten me as to somedifferences in the M-2c locomotives? The Sunset HO import has Baker valve gear,BL feedwater heater, single cylinder stoker motor and those odd cylinders withthe port on the side between the piston and valve chambers. What was thatfor? Which engines do these modelsrepresent. I haven't found a picture of the fireman's side of a Baker engineyet. Seems most M-2 engines had Walschaerts vg. I'd like to paint and letterthem as specific engines with correct details. Any help would be greatlyappreciated!
