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.

I thought the main reason the PO railway shut was that the Royal Mail
changed the way that it sorted mail, so that the old railway didn't
serve the modern processes efficiently?
