Most conveniently, what they do with some trains at the French-
Spanish border: slide the wheels along the axles to fit the other
gauge. Other solutions include mixed-gauge track, bogie changing,
and (of course) having the passengers change trains.
In the latter option it seems a bit pointless going to the expense of
building a tunnel.
According to my Jane's world railways the high speed line into Madrid
is standard gauge, not the normal Spanish broad gauge.
What's that got to do with a tunnel under the Irish Sea?
It relates to how you deal with the problem of the UK being on standard
gauge and Ireland being on broad gauge, which would be raised by the
construction of such a tunnel - the analogy is that if you're going to
build the tunnel, you might as well build the high-speed link on the Irish
side to standard gauge, since it won't have normal Irish trains running on
it anyway.
