I travelled from West Hamstead To Tulse Hill the other day; the first time I've been through the Snow Hill Tunnel route for quite some time. The journey between St. Pancras and Farringdon was much faster and smoother than previously. Before, the trains used to move very slowly and the wheels used to screech as they negotiated the tight bends.

I had always assumed that the reason for the slow movement and the loud screeching was that the line had originally been built cheaply and that there was no scope for re-aligning the track. Does anyone know how much work has been done on the section between Farringdon and St. Pancras International and if further improvements are planned?

In the 1960s my route to work was Palmers Green to Moorgate. Does the route between Farringdon and Finsbury Park still exist?
