Buses on Route 507, which travels between Waterloo and Victoria, will be

Why not double-deckers?



Because the roof at Waterloo is too low?


Because double deckers are unsuitable for Red Arrow routes, which have
always (since being introduced in the 1960s) operated as high-volume
standee single decker buses). On the 521, of course, the Aldwych subway
forces single deck use anyway, but there are operational reasons too.
