MV Class-70 Engines Here is what I have and a few thoughts on the matter: VS&P 2-8-2's of 1915 and following VS&P/A&V Baldwins built through 1924 for them with Hodge trailer truck, 22 x 28 cylinders and were pretty much the Baldwin standard short line offering as compared to industrial engine designs as covered in R&LHS's Railroad History #196. The MV 70's were nominally 100 ton engines. Baldwin pursued a number of small common carriers like the MV, such as the GM&N, Ft.S&W, A&V, VS&P and perhaps a few others with this basic design. The MV received theirs in 1917, 1920, and 1922. In 1926, the IC acquired the A&V/VS&P and its Mikes of this design, later converting many of them to 0-8-0 type and modifying them other ways, some with higher boiler pressure and optimistic hopes of higher useful tractive effort. The MV engines initially had their pops set for 185 psi working pressure, later raised to 200 psi-but they continued to list the tractive effort as 37,370 lbs. I think there was a degree of carelessness in the reporting specifications in the diagrams, timetables and stencil data shown on the cabs under the road numbers. The IC diagram shows data as close to the MV engines as I can find; I don't trust the MV diagram 100%, thinking that Baldwin would not make such minor differences in wheel bases on a so called standard design. Photographs between the MV 70's and the other lines versions of this design show little if any basic differences except for accessories, running boards, gadget locations. The MV photos would have to be the governing image for the model makers, and perhaps the wheel base and overall dimensions as shown on the MV diagram BUT the MV Timetable shows the driver wheel base as 15' 0" and engine wheel base as 31' 8" and overall engine and tender as 75'. New tenders were bought by the MV for some engines-I think for some or all the 70's but I can't find material on this at this time.
