PASSENGERS at Glasgow Central have shared their hopes and concerns over a possible sleeper train to mainland Europe. The reaction comes after a working group began exploring whether the Caledonian Sleeper service could eventually extend beyond the UK. Glasgow Central could become part of a future sleeper connection to mainland Europe if plans progress. The Caledonian Sleeper currently connects Scotland with London, including services from Glasgow, but does not operate any European routes. No decision has yet been made on whether a direct Caledonian Sleeper route to mainland Europe will go ahead.
