(Yesterday, 12:39 pm)morritt89 wrote So is the issue the vehicles or lack of available infrastructure (charging facilities) whilst they are on route (a similar issue to electric cars in some respects)?
Is there actually any electric buses on the market that could theoretically meet the range required for the 21?
For the first bit, I'd say both.
You can have the best electric vehicle in the world, but if it doesn't have the mileage it's diesel equivalent has, then you can have all the charging infrastructure in the world - it still isn't going to sort out the current running boards or route demands.
For the second bit.
Theres absolutely no way I'd have the brass neck to go cap in hand to the government and make a business case for a vehicle purchase, knowing the vehicle chosen isn't suitable.
