The NGT trolleybus scheme would produce nothing that could not be achieved by conventional double decker buses in well maintained condition, on good roads, and to a specification at least compatible with that of Yorkshire Coastliner and Harrogate and District (Transdev) vehicles. Bendy buses, diesel or trolley, increase congestion because of their 80% increase in length with no increase in payload and a diesel bendy bus is roughly twice the cost of the double decker. The trolley bus is dearer still, partly on account of the smaller production volume. Mainly used in former Russian and Eurasion states the penalties in this country of using small isolated fleets with regard to spares and operating costs should not be under estimated. There are none currently in Britain and relatively few in Western Europe.
