GN2276 - Is that word "consist"? If so, a typical consist or train for an SCL (ex-SAL) SDP-35 would have been a first class freight or perishable train. Very likely in company with any diesel (typically modern) that SCL had. On the SAL, SDP-35's saw service on both passenger and freight trains and for a year or two locomotive assignments didn't change much after the merger. On the SAL it appeared that 1100 to 1105 typically saw duty on #3 and 4 (the Richmond-Atlanta mail and express) or on the "Silver Comet" Richmond - Birmingham passenger. The others were typically in freight service with 3 or 4 units being typical power for TT-23, Seaboards' very fast piggy-back. Although again, SAL was very much a "couple up the ready track" railroad with SDP's coupled up o everything from GP-7's to E-8's. Wihin a year or two of the merger SALs' 20 and ACLs' 1 SDP-35 were put into freight service and had their s/g's removed.
