That depends on how your railway is powerd: if it electric and not from
fossil fuel, its 100% greener..

That't a very big if.

its actually not an 'if' its a 'when'.

Fuel prices wont get lower, so other ways to generate will become cost
effective. Period. In fact they already are. Even *windmills* at current
prices are nearing break even, with fuel..
