There were a number of threads about locomotive servicing here on MRH forums with different key aspects.

Model Railroader has The Model Railroader's Guide to Locomotive Servicing Terminals

Then there were two books by Thomas W. Dixon, Jr. from TLC Publishing:

Steam and Diesel Locomotive Terminals and Service Facilities

Steam Locomotive Coaling Stations and Diesel Locomotive Fueling Facilities

The first contains N&W's Ultra-Modern Steam Terminals, the second details the stations in a facility.

Here is a nice video about

Here is a nice video about modern steam made while they were still in revenue service on the N&W. In addition to some action footage it shows the servicing of the locomotives the way the N&W did it.

It is from YouTube so I believe there are no issues with posting it here.

the link back follows if you desire to browse other videos.

sorry the link back produced a second copy of the video.

I hope you find this helpful.

Here is a track chart from

Here is a track chart from 1949 and some photos from the late 1950s of the IC division point locomotive servicing facilities in the late 1950s.

Centralia was a division point facility where the Illinois Division, Springfield Division and the St Louis Division met. There was a 100 foot turntable and a 48 stall roundhouse.  9 stalls of the roundhouse were set up with large overhead cranes and they could do any level of maintenance there.  There was a large machine shop attached to the locomotive erection stalls of the roundhouse and there were mine type tracks that were used to move the large components from the erection building to the machine shop. 

The tracks to the south of the roundhouse served the engine facility and the ones to the north served the car shops.  The yards (6 of them) were south of the engine service facility.  When locomotives came off the road their initial inspection was done in an open inspection pits before they ever got to the roundhouse.  The ash pit was between the open air inspection pits and the roundhouse.

The sand house and tower was just south of the machine shop and the coaling tower was south of that.

This is a view taken in I believe 1958 by Don Morice from the top of the coaling tower. You can see the erection building in the roundhouse with the machine shop just behind it on the left side of the photo.  The sand tower is behind the machine shop.  The brick building between the power house and the machine shop contains lockers and wash up facilities for the engine crews.  The tank cars on one of the ready tracks are for fueling the diesels as there were no diesel fuel facilities there at the time.

3500 series 0-8-0 switchers at the sand tower.

Hoppers under the coaling tower.  Another Don Morice photo.

looking south from the roundhouse.  Note the water column in front of the sand tower.

This is a post card showing the Centralia engine facility as it looked right after it was constructed in 1912.

Hope this helps.
