Thanks.

What would you call it?

I don't think we'd have a name as we don't have any - the UK is all
high platformed, or for the rare low ones (not US low) there are
usually wooden steps left on the platform.

The only thing even vaguely like it is the retractable step on
Metrolink trams in Manchester, but I think the platforms are now all
high so they are unused now. All other tram systems in the UK are
all low platform with low floor trams.
