Nice to see some good news. Here in the W Mids, like few other
places, there is choice to London, quick and expensive, and 2x slow
and comparatively cheap. The excellent Chiltern Railways is part of
the (public) Deutsche Bahn. Wouldn't you know it?

IIRC the same was true when I used the Chiltern line in the 1990s, well
before its (ultimate) owner was Deutchse Bahn. Correlation does not
imply causation?
