That may be an issue, but AFAIK the main issue was that there is a tram
junction between the two crossings, and one of the crossings has
significantly more trams than the other. At the crossing with fewer trams,
the tramlines are inside the barriers, whereas at the crossing with more
trams the tram tracks were required to be outside the barriers, pothrerwise
the barriers would be closed for too much of the time.

One of the pics referred to somewhere up there said the latter barriers
went up and down like a bride's nightie .... *searching wildly for utl
relevance* It's a good thing TABAWTKB didn't have a level crossing !
