I can't help noticing that there is a continuous strip of undeveloped river

this corridor makes financial sense.

I'm also not sure that PRT is very suitable for this kind of connection,
where a lot of people will arrive (at the PRT stop at Feltham) together
from a train, but no-one will arrive in between trains. The reverse
direction is better, because people arriving from planes don't bunch
together quite so much (given customs etc.).
