Interesting technology but there seems to be a negative view of the
railway.

I wonder what they'd see if they pointed their telescopes at the inner
ring road or at the nearby M1.

Visually at least the oil smoke emitted from a valenta after a period  
idling is likely to be worse than anything experienced from a road vehicle.

At Nottingham on the platform usually occupied by an HST most of 
the time, there is a huge black patch on the edge of the roof just 
where the London-end power car's exhaust outlet sits!

The problem with large diesel engines as used in locos is that when it's
idling, oil can build up in the silencer(s) which comes out half burnt
when the engine is revved up. The worst locos for this were the
otherwise superb Deltics.

I expect its just that the railway pollution occurs in bursts as the
trains leave, so is easy to see, whereas the road pollution is more or
less constant so there are no changes to be seen.
