I wouldn't have thought an employee timetable would help with that.

 

Really, do you have a recommendation then?

They may not be easy to find-- especially if you're hoping to learn what the usual hp/ton was for a given train symbol. Usually when a railroad produces a table of "tonnage ratings" they mean the tonnages that the various units can barely stagger over the subdivision with.

In the end it may not be really relevant for what I’m trying to do. I’m trying to get an idea of average train length so I can determine how long I need each layout LDE needs to be (based on train length) but given my space limitations I don’t think I can get that close to a prototypical train length even though I’m modeling in N scale. For instance present day BNSF trains are huge; 120-150 well stack trains are common. That’s about 9000’ feet long or about 56 feet in N scale (I thought perhaps that they may not have been as large 15 years ago). 

 

So I guess I really need to nail down traffic types and schedules.

 

Thanks anyway

I just ordered a 1994 employee timetable to help me nail down traffic types and frequency

ATSF Seligman sub (N. Arizona) loco tonnage ratings
Posted by BDF on Wednesday, November 5, 2008 12:19 PM

Hey there, I’m planning on modeling the twilight of the AT&SF (last 5 to 10 years) over the Arizona divide (Seligman sub).  If I’m not mistaken the sub itself is mostly through traffic with the majority being intermodal (pigs and stacks).  I just ordered a 1994 employee timetable to help me nail down traffic types and frequency but I’d like to know if anyone has locomotive tonnage ratings for this sub and or average train size per train type.

 

Thanks for any help!
