Does anybody have the tonnage ratings for: Class R Mikes, 500 series 2000 H.P. FM diesels, and the 1500/1600 H.P. 200 series? Seems odd that the Class R's normally ran alone as did the 2000 H.P FMs. Then the road bought the smaller FMs and almost immediately MU'd them with their bigger brothers. Did train weights actually increase to tha point of needing 3500-3600 H.P. to get over the road?

AC&Y employee timetable #42, June 27, 1948 has tonnage ratings for "Class R Engines 402-410 and Diesel Engines 500 Class", and "Class M Engines 320-324". It's pretty complex. Eastbound it's broken down into segments: Delphos-Bluffton-Carey-New London-Spencer-Brittain with a table for each (1 thru 6 + L). Westbound segments are: Brittain-Belt Jct.-Spencer-Huntington-Carey-Bluffton-Delphos with same tables. Simple enough? Then each table is broken down into number of cars from 45 to 120 for the Rs and 500s, and 25-90 cars for the Ms. If that's not enough, it further has "Temperatures Governing Reduced Rating" from A thru E.

If I can get the museum* to scan the page, I'll post it.

N&W employee timetable, Lake Region- Pittsburgh Division #5, April 8, 1973 has tonnage ratings for "AC&Y District" broken down into 3 segments EB: Delphos-Carey-Spencer-Brittain. WB: Brittain-Belt Jct.-Spencer-New London-Carey-Delphos. While not as complex as the AC&Y ETT, it has locomotives in 7 groups that includes everything from GP7s to SD45s and C-630s. No F7s listed. (Did N&W ever run those big 6 xle monsters on the former AC&Y?) Again, I'll see if I can get this scanned with the above.

Dale,
I scanned the tonnage rating tables mentioned earlier to the ACYHS. Haven't seen them. Have they been forwarded to you? If you still want them, send your e-mail address to me 1oldgoat@centurytel.net and I'll send them directly to you.

OS
DanO.

Dano: 'Don't know how I missed your posting/offer to email tonnage ratings back in March. I normally scan the ACYHS site fairly frequently looking for anything new. However, with that said, if your offer is still good; I'd really appreciate your emailing the tables.. send to dalefairfax@hotmail.com. Thanks a bunch.

One of my friend used to have this. Let me ask him about this. He will surely help it.
