Venues Continental
NEXT •year's Continental show calendar includes four major events at which commercial vehicles will be exhibited. Starting off with Geneva (January 21), Amsterdam (February 9), Belgrade (March 31) and Paris (October 5) are the other venues in a season which will culminate in the joint UK car and truck show at the National Exhibition Centre, Birmingham, opening on October 20.
There will also be several thematic shows in which road transport exhibits will feature prominently such as "Total Transport" which, as a successor to the former Nedex Show, will occupy the Ahoy Halls in Rotterdam from April 18 to 22 and the Hanover Fair starting on April 19. Interest at the latter is enhanced by the participation of a good. crosssection of the European cv industry as well as a number of specialist bodybuilders.
The huge biennial Expomat construction equipment exhibition at Paris (May 19) will again bring together vehicle builders from many countries as well as low-loaders, tippers and heavy haulage equipment.
As already mentioned (CM October 21) passenger transport will be the subject of an exhibition at Gothenburg, Sweden, from June 27 to 30 while the "Transport '78" show at Munich (October 17) has been enlarged to cover freight as well as passenger transport developments and equipment, An earlier event at Munich (June 5 to 10) is aimed at users of municipal and public cleansing vehicles and equipment.
For more transport dates, both in the UK, on the Continent and beyond, clip out our International Calendar appearing in CM on December 30. -WHILE —Russia and Eastern European countries continue to use trolleybuses, the strong revival of interest in the West has been impeded by the dearth of manufacturers still making them.
However, Berliet and Volvo have recently adapted current city bus chassis to electric traction. Several cities in France, Italy and Switzerland are already using these vehicles in new or enlarged trolleybus networks.
A third manufacturer, Daimler-Benz, is using the recently-introduced G.305 pusher artic. as the basis for a ''duo bus' diesel-electric derivative now being prepared for service in a town where the overhead wires only cover part of the route.
The Berliet ER 100 trolleybus, for which Grenoble, Lyon, Marseilles and Limoges have placed sizeable orders, has also formed the basis for a licence-built prototype in Poland. Warsaw, which had only removed the remaining overhead trolleybus installation as recently as 1973, is once again working on a re-introduction programme for trolleybuses — they are due to start service by the end of '78 — and will probably use Jelcz-Berliet based units while other Polish systems continue to be supplied with Russian-built vehicles.
In the Netherlands where Arnhem is this month extending trolleybus service to two new terminals (British-based Leyland/Vereul units are still in use there) an interesting proposal concerns the introduction of a wholly new 51 route-km system serving the North Ams area.
