Attached a picture (not mine) of some buses in my city during a huge blizzard, back in the 1960's. Travel was eventually shut down, which is unusual as no matter the winter conditions things rarely shut down here.
When I was a teenager (1960's), I used to work for the city transit system. City buses we used were GM, Canadian Car, Flxible and I think we were the only place in North America that had a few Mitsubishi buses...they had very big diesel V8's. The buses were generally 90-95 passenger units...this would include those sitting down and standing.
The climate here, can range from -40 C to 40 + C and we usually have winters from early November till early April and the snow/ice usually stays all winter without much melting.
So the buses have to be very well built to survive.
It's true that in France there are many museums dedicated to the technical heritage, but I think that it's common to all industrialized countries, not particular to France.We have a lot of museums, but not as many vehicle museums here as I would like. We also have a lot of vintage car enthusiasts who display their cars in the summer. Not unusual to have 150-200 cars at a show sometimes. Occasionally many more if there is a special event. Most of the cars are vintage American, hot rods and classic.
I'm not a great traveler but enough to note that I saw many examples like this bus museum in western countries and never in countries less advanced or being developing.
It's not their fault, I think that these countries have, for the moment, not enough possibilities, time, money and opportunities to devote them to this task.
I'm sure that there are in these countries many people like us, who would like to preserve and maintain their technical heritage, but they have not the means in time and money.
I agree. We are very lucky in the G8 countries to have sufficient disposable money to use on our hobbies.
But, I'm afraid for many of them it's too late, and even if they reach at last the financial ease which allows to give time for preservation, there is no more anything to restore...
For instance in China it's almost a miracle to find any really old architectural heritage excepted the main ones (forbidden city, some temples etc etc) because nearly all has been destroyed during the first half of XXth century. So, concerning technical heritage...
I find in North America, that although some grand old buildings have been torn down there have been efforts made to maintain and rebuild older buildings that have heritage.
To come back to this bus in spite of some research I didn't find any technical informations excepted 4 cylinder 35 HP. Nothing about compression ratio for instance.I would think that the torque of that bus engine would be considerable due to it's large capacity. Thanks for checking on the tech info.
I suppose as you that the compression ration was not very high, it was not possible at this time.
However I have found some interesting photos of this period !
Wonderful photos. They provide an idea of motor life back in earlier years.
