Early versions of road-rail vehicles are described, more recent interest in combination cars in reviewed, arguments are presented for road-rail service, and the study of the service in Hartford, Connecticut is outlined. A possible solution of the conflict of who and how many shall operate while the intermodal vehicle is on rails, is the state takeover or subsidization of little-used railroad lines and their operation under a new code of rules. In Hartford, 5 state and 3 federal bodies participated in a 2-phase study on the alternatives of coverting a rail line to an exclusive bus road and equipping it for road-rail vehicles. It was shown that conversion to a bus road would cost $6,109,123 while equipping for the road-rail would cost $1,817,244. An engineering study found the project wholly unsuitable as a transit enterprise. It is indicated that an laternative preferable to extensive track upgrading on many lines is improvement of the vehicle technology to allow a smooth ride even on rough track. Calculations for a schedule for the vehicle must include road-rail-road conversion times. Comments are also made relating to operating speeds and areas of service suitable for road rail. The theory of using a rail line in lieu of a crowded highway, and of increasing the versatility of a rail vehicle by making it capable of road running is considered valid.
