Gangway between two NSB B7 coaches, line Bergen - Oslo, 2005-08-14.
The airtight gangways were something new for the B7 generation.
Unfortunately, unlike SIG-II gangways, they cannot be coupled to
standard rubber gangways, which means that some "transition cars"
(B7-6 and FR7-3) had to be created (probably by rebuilding).
