Ships certainly were - the Scottish slang term 'steaming' for drunkenness comes from the fact that pleasure steamers weren't restricted by licencing laws. This seems to exist at least from the Customs and Exise Act 1952 which exempted passenger aircraft, passenger vessels, and railway passenger vehicles. Even public houses could serve alcohol to 'bona fide' travellers at times when they would otherwise be required to be closed.certainly not now, but then was an era of much stricter licensing so it may well have been the case in theory, hence my musing, though I rather suspect trains and ships (in domestic waters) etc may have been exempt back then.
That clearly changed at some point - the Licencing Act 1872 specifically permitted the sale of alcohol at railway stations to 'persons arriving or departing by railroad'. Railway stations were also the only place which allowed children under 14 to be in a bar after that restriction was brought in.Not they didn't, but specifically only on trains themselves. At soon as you stepped on the platform normal laws applied, an enthusiastic bar steward got done for selling alcohol on a platform before the departure of a train at some time in the 1970s.
