Looks like a sign to denote some infrastructure (track /
signalling / etc.) feature to me. Although, does it stand for
Temporary Speed Bump?

I wonder if "TSB" stands for track-side box ... but no idea what it
means if that is the case!

Train-op Sushi Bar?

It's a similar sign to the "newer style asset sign" shown at
http://www.districtlinephotos.co.uk/...allery_17.html,
which is also in a non-Johnston typeface.

According to my resident expert, there is no good reason the infracos
haven't used the Johnston typeface.
