Subjected to The One Show at the parents' this evening, I noticed a few
minutes on the Post Office Railway. A mixture of historical film and
current, ending with a brief trip on the line today (albeit dressed up
for Christmas with obligatory cuteness for early evening BBC1).

skip to 39' 11" for the film which lasts about 4 minutes.

Obviously it wasn't the first electrified railway in the world as the
museum manager says, but despite that the segment is well worth viewing.
