The line is ideal for conversion to tram operation with a Morden
diversion between South Merton and Morden South.

I don't think that will be very popular at Wimbledon Chase, unless it
is looped into Dundonald Road but that would miss out Wimbledon.
Presently Wimbledon tram stop is a single platform in a very
constrained site hiw many trains per hour could it support?

The patronage figure
are poor. Trains from Kingston, Raynes Park, Epsom etc could then be
diverted via Tooting, Streatham and onto the Thameslink system.

This would require flying junctions or diveunders to get from the Up
Slow line to the Tooting connection - a huge capital cost. Also one
reason the ELLX did not go to Wimbledon as paths were in short supply
on the Tooting line so, all in all, not very feasible.
