DUAL MODE BUSES

DUOBUSSAR. LEDBUSSAR MED TRAAD-/DIESELDRIFT FOER SVENSKA FOERHAALLANDEN

Dual Mode Buses with combined trolley and diesel propulsion, i.e. buses with two propulsion systems that can be used independently of each other, have been regarded by many as corresponding to the environmental requirements for public transport in city areas. The Dual Mode Bus is however substantially more expensive and, in addition, the trolley infrastructure means a large investment. Two questions require answers: (1) Is it possible to design a simple and cheaper technique without reducing performance? (2) How large is a predicted Swedish Dual Mode Bus market and would the bus price be favourable thanks to large production volumes? The first question is answered by the authors of the first part of the report, which is a preliminary study of an earlier released and now further developed technical idea. From the study it may be seen that hydraulic transmission of the driving power, when operating under overhead wire, might be a simplification and lead to lower prices. The second part of the report summarizes a questionnaire distributed to a number of major Swedish public transport companies. It appears from this that the market situation requires a careful attitude and that production volumes for the time being may be expected to be low. The same is true if the cheaper bus was made available on the market. (Author/TRRL)
