That should lead to a few questions about rail policy differences between
Scotland and England - is it the Alloa - Kincardine route that goes
through
or near Brown's constituency?

AIUI not through, or even very close to his constituency - but by taking the
coal trains for Kincardine Power Station away from the Forth Bridge it
should improve the performance of the passenger trains which do serve
Kirkcaldy.
