Alcohol should be banned on all trains - it would solve a lot of problems in my opinion.
Am I correct in saying that a TOC needs to pay significant amounts of money in "fines" when a train is delayed by more than 5/10 minutes? Would this still apply when you have "disruptive passengers?" I suspect it does, but I don't think it's a very good idea, as it discourages TOC's from properly dealing with disruptive passengers to avoid being "fined."
No, no, no! Alcohol banned on trains? The majority of people causing disruption when under the influence have already had enough BEFORE boarding the train. I've been on trains with various football supporters, QPR, Huddersfield, Manchester City, Aston Villa, Birmingham, Stockport County, Sheffield Wednesday, Manchester United, Southampton and NEVER experienced a problem - all those groups had either been/were drinking last time I boarded a train under the (severe

) influence I caused no problems and had had my drink in various pubs before boarding.
The morons who cause disruption when they have been drinking cannot handle the damn stuff. I've never once abused a member of the train crew when very drunk. Most members of society can handle their alcohol. I can hold a perfect conservation after a skinful in a quiet tone (slurred though

) and I'm 18, my age group is supposedly the worst of society yet I don't know anyone whose disruptive after a load of drink. True colours of people show through drink.
Its the passengers and not always the alcohol that causes the problem.
