C&S Operation

The Claremore & Southern Railroad is actually four railroads in one.  The C&S being the principal railroad, connects with   1. The Missouri-Pacific RR   2. The Tulsa Sapulpa-Union RR  and 3. The Sand Springs RR.  The heart of the operation of all four railroads is the Osage Yard. This yard is the source of traffic for all the other railroads that the C&S connects with.

Yard Operations

The C&S is based on the Cherokee Subdivision of the Frisco Railroad. It currently operates between Monett, MO and Oklahoma City, OK. The major yard is the Osage yard, which is patterned after Frisco’s Cherokee Yard in Tulsa, OK.  As in the prototype, operation in Osage yard is the key to a smooth operation on the railroad. While yard operations are largely invisible to road crews, the smooth and efficient movement of several hundred cars through Osage Yard during a typical operating session is essential to a successful operating session. The drill crew is almost constantly busy classifying cars while the trimmer crew makes up departing trains. The yardmaster is kept busy directing this activity and handling arrivals and departures. A hostler moves engines,  stages power for departing trains and delivers cars to the Sand Springs Interchange.

A second yard is located in Claremore, OK where the C&S interchanges traffic with the Missouri Pacific (known as the MOP to C&S crews). One of the unique things about the C&S is that it models three separate railroads. The primary railroad is the dispatcher controlled: C&S. The secondary railroad (but not a branch line) is the Missouri Pacific (MOP) which is operated as a “dark” railroad. The MOP runs independently of the C&S and operates between Coffeyville, KS and Ft. Smith, AR with several industrial customers in the towns of Muskogee, OK, Oolagah, OK and Coffeyville, KS as well as engine facilities at its Coffeyville division point. The MOP is the major source of traffic for the C&S.

A third railroad is the Sand Springs Railroad which operates from the interchange trackage to its own teritory. A major source of revenue for the Sand Springs RR is the Armco Steel Mill at the end of their line. The other nine customers keep the Sand Spring Railroad in business. 

The fourth railroad is the Tulsa Sapulpa-Union Railway.  Its biggest customer is the Mid-Continent Oil Refinery.  There is enough traffic and car movement to keep two operators hopping for a whole session.

 Era & Scale

The railroad is in HO scale set in Summer of 1955 .  Steam is almost gone.  Most of the power is now those stinky diesel things.

 Motive Power and Rolling Stock

Engine types on the C&S and the other three roads include primarily EMD F3s, both A/B/A sets and single engines, and GP-7s. In addition there are a couple of SD7s, a few RS1s, a pair of NW2s, an F7, an FT and a pair of E8s in the engine shop being overhauled for passenger service on the MOP.

Rolling stock which operates with car card waybills includes over 350 box cars, 50+ flat cars, 100 covered gondola cars and 80 or so hopper cars.

Non waybilled cars include a unit train of reefer cars, Trailer on Flat Cars,  2 Hopper Car Unit Trains and a Tanker Car Unit train along with a dozen or more C&S crummys and a number of passenger cars.


The layout is an island design which is “sincere”, that is west is always to the operator’s left and east to the right. There are no duckunders and the railroad does not double back on itself. The 12-track staging yard is isolated from the layout by partitions but is completely visible when the operator is in the staging yard area. The only hidden track on the layout is the reversing loop, which represents Ft. Smith on the MOP. The C & S mainline is better than 275 feet long .  There are 85 industrials  that all four railroads serve. The MOP has a four track yard at Coffeyville, a 175 foot long mainline and 20 industrial sidings.  Mainline height varies from 42″ in staging to 52″ as it passes above and behind Oologah, OK.

TSU has a 2 percent grade clinb from the Osage Yard Connection to the oil refinery.  From then on it is level sailing, all the way to the power plant.
