So the electricity used to power the railway was zero carbon, was it?
Didn't Britain have any coal, oil or gas fired power stations when the
Post Office Railway operated?

Gas produces less CO2 per unit work than petrol or diesel. Also a significant
amount still (despite the best efforts of the Campaign of Nuclear Dunces and
Greenpratts) comes from nuclear power.

The exhaust fumes are at the power stations. Lorries and vans are
needed to collect the mail and bring it to the railway, and then to
distribute it.

The lorries are still being used to take the mail to the sorting offices
the railway joins up. Except now they're needed inbetween those offices too.
