There's a surprise - more interference from the EU in things it has no
business being concerned with.

It was the EU taking its lead from the UK, in an effort to encourage open
access and international train operators. The aim is to deliver a better,
cheaper service to customers through competition and innovation. It's
worked in quite a few countries, but the old state monopolies, particularly
DB and SNCF, work hard to block it.

Obviously its impossible to know what state BR would be in today if it had
continued but been given the same level of funding as the current system, but
I suspect it wouldn't have been much different plus there's a good chance we'd
have more R&D in this country.

This prompted the works to allow gauge clearance as well as removing

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

quote

Réseau ferré de France (RFF, French: French Rail Network) was a French
company which owned and maintained the French national railway network from
1997 to 2014. The company was formed with the rail assets of SNCF in 1997.
Afterwards, the trains were operated by the SNCF, the national railway
company, but due to European Union Directive 91/440, the Government of
France was required to separate train operations from the railway
infrastructure. On 1 January 2015, RFF became SNCF Réseau, the operational
assets of SNCF became SNCF Mobilités, and both groups were placed under the
control of SNCF.[1]

IIRC vertical curves rather than horizontal or was that the Central
Line ? Gauging runs at low speed hadn't sufficiently imitated normal
running conditions.


Don't know TBH. I do know the 2009 stock on the victoria line is too wide
for other tube lines, though I suspect that is more due to profile than actual
max width. They're definately more slab sided than other stock.



1992 stock are also very flat-sided, though the 2009 stock seems to have
higher 'shoulders' IYSWIM.

Yes they do which makes standing next to the door much more comfortable than
in other tube stocks as you're not hunched over like quasimodo. I imagine
that extra shoulder width on curves is the issue.

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...
