and public charge points could be installed with increasing frequency.
This is not working, local we had two charge points, they took the space needed to park three cars. Then they installed another 4, yes space needed for 6 normal cars, and they wanted to stop normal cars parking by chargers, and with the first 2, there is a problem where the EV user has to move their car to make room for others to use the charger.
Where I work we have space for around 60 cars, it is not enough, even as it stands, a train (I work at a station) can carry around 100 passengers, so the time between train arriving, then departing again, need spaces for around 200 people, OK some cars may have 6 people in them, but summer we have to revert to parking on the grass as it is.
Cutting parking down by 1/3 is simply not an option. I saw a report of how Rhyl can now charge 50 cars, come on, it's a sea side town, that relies on visitors, forget 50 cars, even 500 cars would not be enough.
We already have places that use diesel generators to supply EV charging points, the main point about trains, they run mainly on the flat, OK local railway 1:29 which is steep, but one engine can pull 4 carriages, even on our steep line, that's a lot of people for around 180 HP. OK a bit slow, 16 MPH speed limit, but this is Wales even cars have 20 MPH speed limit in the towns.
