Yes, the D.C. lines are both in single bore tunnels from Camden Junction to South Hampstead, and at the Camden end they have each have tunnelled junctions where trains can run to/from the North London Line. That and St Pancras are the best examples I can think of in the spirit of the question, as they are full running junctions, and not just a station approach where the tracks are fanning out.Isn't there one somewhere on the approaches to Euston?
At King's Cross, the facing crossover to access the North London Line incline / HS1 connection is located within the Slow Line bore of Copenhagen Tunnel.Whichever tunnel the Strat*gic Res*rve has been moved to now must have a junction?
More seriously doesn’t the new Kings Cross layout add more junctions than now within the tunnels, some of which are well before the station?
I was noting that the current works provide a load more, ie in all 3 Gasworks Tunnels, and additionally one in the Copenhagen fast.At King's Cross, the facing crossover to access the North London Line incline / HS1 connection is located within the Slow Line bore of Copenhagen Tunnel.
Gasworks tunnel does not, IIRC, have any S&C located within either bore.
and nearby there's the underground roundabout at Canary Wharf.Also OT, but there’s technically one in the Limehouse Link in East London.
Bad accident there in 1939 - 1 dead, 161 injured. See the Railway Archive Stobcross WestThere’s an abandoned junction in the Eastbound tunnel between Partick and Exhibition Centre that used to lead to Kelvinbridge and the Botanic Gardens. This was the route the water took when the Kelvin flooded at Kelvinbridge and left the whole low level line and two 314s almost totally submerged.
