Exploring the furthest reaches Barbican station I noticed a third
tunnel mouth at the western end of the platforms, between the TL and
KU tunnels, and what looked like a ground frame, still connected to
point rods disaooearing into the ballast, between the TL tracks. Were
these related to the former Smithfield goods station? ( I thought
Smithfield goods was south of the TL tracks, as showm at
http://www.londonrailways.net/snowhill.htm.)

I think there was a ground frame (released from West Hampstead PSB) at the
west end of Barbican Station up until the late 80s. IIRC this controlled a
trailing crossover between the two TL lines and was recovered (at least as
far as the interlocking was concerned) as part of a capacity upgrade project
c.1989.

I should have a signalling plan somewhere but it may take a while to dig it
out.
