The reason why they have not proceeded with the NLL option
is that it would be a slower line, there are greater problems
with conflicts with NLL and freight services than with the
tunnel option, and a couple of level crossings which can't
easily be avoided without tunnels.

I find it hard to believe that a couple of level crossings are even a small
part of the reason for a tunnel costing, what, hundreds of millions? Bollo
Lane, and especially Churchfield Road, are exactly the sort of streets in
which councils erect barriers to prevent rat-running, so closing both roads
at the railway is an obvious and cheap solution.
