Shouldn't they have done that before ordering the new trains?

When the New York City Subway started commissioning and testing what was
then the brand new R-38 in the 60s, they realised that there was loading
no gauge on some of the tighter curves, particularly on the Fulton
Street Line.

This prompted the works to allow gauge clearance as well as removing
some of the walkways around towers (signal boxes).

IIRC something similar happened when the 73 stock arrived on the Piccadilly
line. The new cars were longer and so the throw was greater and the tunnels
linings around south ken had to be "shaved".


The 2014 French example is the biggest I'm aware of.

Oops. Also it seems I'm rather out of date on French railways. When did SNCF
become a train operator only?

The EU mandated separation of infrastructure from train operation,
following the pattern established in the UK by privatisation.

Of course, the UK never had any influence in the EU...
