This video is about 6 weeks old, but I don't recall seeing it before. Is
it my imagination or is the name text over the entrance to TCR station
in a font other than Johnson?

Well spotted. Yes, the text over the entrance for TCR and also
Paddington have C, G and R that are quite different to those letters
in Johnston. They look like Helvetica to me, though they might be
the similar Rail Alphabet which was British Rail's corporate typeface
from 1965 until the late 80s.

Liverpool Street as well unless I'm mistaken. Looked more like Helvetica
than Rail Alphabet to me although the shots are brief.
