CN auto transporter build
Between 1956 and 1959 Canadian National took delivery of double deck auto transporter cars that were some of the earliest auto racks produced. CN took delivery of a total of 75 x 75' cars and 75 x 57' cars. These cars were intended to replace the 40 and 50 foot boxcars that were the primary transportation mode for automobiles on the railways. The 57 foot cars were almost immediately obsolete in their intended service as they were only able to transport 6 automobiles. The 75' cars were able to transport 8 automobiles so were a bit more useable in their intended service. These cars were not to be interchanged so primarily stayed on CN trackage for their careers. 8 of the 57' cars were used in Car Go Rail service on the Super Continental passenger train service in the 1970's. As well other 57' cars were converted to transport other items like boats and roof trusses after they were superseded by enclosed autoracks. One was converted to a cattle car! More i
