Omnibus (in general) - 9


In comparison, the bus also appears to have the edge over other forms of electric-powered road-users. Trolley buses have been around since the beginning of the last century. All the tests done to replace their relatively simple current tapping have, up to now, been unsuccessful. Only a certain amount of 'hybridizing' by adding a Diesel engine and the storage of a certain amount of current to cover stretches where no overhead power lines are available, appears to be feasible at the moment.

In some cities, e.g., Lyon in France, one can see buses with a raised roof driving around. These are mostly natural-gas storage tanks. The original Diesel engine has however, been changed quite a bit, because it now needs the compression and the altered crank mechanism of a petrol engine, which in vehicles of this size, is simply not to be had, particularly not as a high-torque, relatively economic utility engine. It would also require vast changes in the infrastructure of a normal large coach operation.

So, for the time being, the Diesel engine will remain, indeed, very much changed in the area of exhaust-gas because of the ever increasingly strict emission regulations. Even if one is being dazzled by striking hybrids at the utility vehicle-exhibitions, it's still going to take some time, after all, the necessary range of these heavy-weights can only be achieved by the massive application of batteries and these are very expensive, particularly if they have to replaced prematurely.

There is even an extra windscreen-wiper for those
sitting upstairs in the front.

To finish off with, an important change in German legislation must be mentioned. Apparently, the Federal government has also become aware of the fact that buses, as far as energy efficiency is concerned, are coming very close to that of the railway trains. Perhaps this is also why, that after approx. 130 years of urban-bus-service, the long-distance bus service has now been opened up (this was previously not permitted in Germany, to protect the interests of the railways). This means that students or pensioners can travel the entire republic for a fantastic €25! Why primarily this population group? Because they are considered to be particularly aware of the costs, after all, those who are willing to pay the distinctly higher railways prices, can do the trip in some cases, in half the time.

This is how bus-tyres are balanced.
