The DfT remains consistent in its dislike of OHLE 175

As usual, the incompetent DfT only thinks about short term costs of
initial construction, not the long term running / operating costs.

Batteries have a finite life. You can recharge them, but they eventually
deteriorate, hold less charge, and have to be replaced - and they are
not cheap to replace.

Moreover, you use additional energy to convey the weight of the
batteries on every journey, instead of getting energy from fixed
overhead wires to move a vehicle that is lighter due to the absence of

And before anyone suggests fuel cells, they also have finite lives, and
to function, they often rely on the presence of rare, expensive,
precious metals (platinum, palladium, rhodium, etc.)

All of those factors would be included in the appraisal of costs and
benefits of competing options - bus, battery tram, OHLE etc - over the
the life of the project.

I recognise however that many proponents of trams argue that that is the
wrong approach, and that conventional overhead powered trams ought to be
chosen even if they will cost more for the same quantifiable benefits,
because they are just better.
