There's a tweet from Tim this morning reminding us that today is the 157th
anniversary of the opening of the Metropolitan Railway, complete with
then-and-now pictures of Baker Street station:

At opening, there were broad gauge tracks, but narrow platforms; now, there
are visibly wider platforms that take advantage of the narrower tracks. The
skill of the presentation of the original 'look' is very apparent.
