I rode on one in Pilsen, in between beers. The route was punishing. A very long and steep route with lots of hill starts, and urban stop-start at one end. It was fast.
However, that was my impression from a three day visit. Whether it has lasted ot not, I cannot say. But it was certainly getting a gruelling workout.

I saw those a couple of years ago. Rather 'cute' seeing a pantograph on

a bus. But they are a very special case - runs at slow speed though a

compact city centre and then gets a 5 minute recharge/rest break at end

of each 'run'.

They also just pulled the power from the tram network. I followed the

feeders from the bus layover area to the nearby ring tram route, so the

infrastructure for the opportunistic recharge was relatively cheap to

install.

Rome also has small battery electrics plying the old city center - and

their trolleybuses have been running the 'last mile' into the city

terminus on battery for 10 or more years now.

And those Roma trolley buses are not running their original batteries -

I seem to recall reading a tender notice for battery replacement some

time back.

What the Czech's are trying in Prague takes it to a whole new level.

Hope it works out.

Also the cities that are trying these have very strict noise and

pollution rules for their cities - and these rules penalize diesels

quite heavily, even the so called 'clean' diesels. Here the government

seems to believe soot is good for us.
