Am i right in thinking that it's normal double track downward from Barnes
in the direction of Richmond and Reading? And thus that Barnes looks like:

to Hounslow
\ \---------
\ ###
\--------- to
--------------- Clapham Junction
###
---------------
to Richmond

Doesn't that mean that local services via Richmond have to share with
mainline services to Reading? Doesn't that suck? Or is the Reading service
not a 'real' main line?

Thanks,
tom
