Premium Intermodal (trailers) service consisting of conventional Trailer On Flat Car (Piggyback) service, Double Stack Service, featuring well cars carrying two containers per platform stacked one above the other on cars ranging from a single platform to the common five platform cars capable of carrying 10 full size containers each, or various combinations of 20 footers and 48 foot containers. Some of these well cars are also capable of handling wheeled trailers as well. For the double stack service, there were nine terminals  to cater to this service system wide. Some of these served conventional intermodal service as well.

Other intermodal services operated by Conrail involved several runthrough services in conjunction with other railroads. These were as follows: Atlanta Flyer Service, a joint Norfolk Southern-Conrail intermodal service between New York and Atlanta with connections to Birmingham and New Orleans.2.California Connection Service, a joint service between Conrail and the Santa Fe Railway between New York and Los Angles. Trains in this service were symbolled TVLA and LANY, and often ran with Santa Fe power mixed with Conrail road units or solid Santa Fe power lashups.3.Lone Star Special Service, a joint Union Pacific-Conrail service between New York and the Northeast and Dallas, Fort Worth and Houston areas.4. Orange Blossom Special, the piggyback train bearing the name of a famous Seaboard Air Line passenger train which made its final runs in the early 1950s. This was a joint service between Conrail and Seaboard System Railroad and then CSX. For motive power, Conrail relied primarily on EMD GP40-2s, SD40-2s, GE B36-7s and B40-8s for powering these intermodal trains in high speed service. The SD40-2s were particularly useful on the heavier double stack trains, since this six axle locomotive was equally at home in high speed intermodal service or low speed drag freight service. Most intermodal trains operated at up to 70 mph where track conditions and consist of train permitted.  It is Conrail's intermodal franchise that drew the attention of both Norfolk Southern and CSX transportation and helped lead to the split of Conrail's line haul operations between the two railroads. While Conrail focused its intermodal services primarily on Long Haul traffic, CSX, on its part, has been going after both short and long haul traffic on its portion of the Conrail system. A few sample schedules shown below will illustrate what Conrail's intermodal service was all about. Precision blocking of trains, high speed running, dedication of operating personnel all helped make this Conrail freight service competitive with over the road trucking.
