It seems to me that the railway is dismally failing in its duty to provide "reasonable notice" of dry trains (as is required by the bylaws) to innocent customers who are not regular users of problem trains, are not intoxicated, and may be carrying closed alcohol containers for innocent reasons (i.e. Not for consumption during the journey).
So it occurs that with more and more examples of dry trains gradually coming out of the woodwork as this debate continues, is there not a case for the industry to have [at the least] a dedicated webpage that lists dry trains - and make country-wide lists available at other locations such a stations where customers buy tickets. Furthermore, surely it should be incumbent on ticket sellers - including TVMs and websites - to make customers aware of such restrictions when they buy tickets for services.
