I dont think you really need fast trains along this line. There are already
fast trains to Watford Junction from Euston.

The Met extension to Watford Junction will work better -
the trains can run semi-fast south of Harrow-on-the-Hill.

If a crossover at Watford South Junction is installed then trains can run
semi-fast to Harrow-on-the Hill as well.
