I wonder what the source of the authoritative time for the UK
Railway
actually is, now?

At least one railway company gave its staff Eurochron radio
controlled
watches which got their signal from Mainflingen, Germany.


Surely from the atomic clocks at Anthorn, Cumbria?

I don't think Eurochron (Junghans) ever produced a watch which
received
the British time signal, BICBW.

They make at least one wall clock (364/7003.00) which uses DCF and MSF
but Google chucks up some remnants of currently unreachable forum
posts suggesting that some of their wris****ches already had bother
with confusion between German and US transmitters (presumably where
neither had an effectively dominant signal) so MSF might have made
things even worse.


You seem to be suggesting that Eurochron choosing to make a watch which
received the British time signal would have damaged the reception
abilities of their existing products.

For the record, the USA and British broadcasts are the ones that can
interfere with each other under rare weather conditions if you're in
Newfoundland or thereabouts. They are both on 60 kHz, but use different
encoding sequences so interference prevents comprehension of either
signal.


I should have added that the problem occurs regardless of whether the
timepiece in question is designed to decode the American broadcasts, the
British broadcasts or both.

The German signal is on 77.5kHz.
