Unlimited range.

Batteries have a finate range, takes time to charge, and are consumed over time, trolley busses have a much longer life span than battery busses and even normal busses.

until a wire breaks, a tree falls, a bird shorts it, bad weather, and all the unknown variables you have to account for.

Trolly buses were the highlight of my childhood but talking about it with a few engineers, they're very high risk and maintenance. You have to have something predictable, disaster resistant, time tested, low maintenance, cost effective, and idiot proof.

Hopefully some battery tech comes in that doesn't require slave-mining but trolly buses are not the uncertainties.

Ok, so what you are saying is that the bus service should be replaced by rail:

Predictable - No random traffic, vastly imporves reliabillity of the system.

Disaster resistant - Less traffic in the system means less impact of disasters.

Time tested - rail has been used for longer than cars/busses.

Cost effective - After a large initial investment the large capacity of the system compensates for the large cost.

Idiot proof - this does not exist, but rail gets close with a lot of added control and safety systems to improve safety and reliabillity.
