Dear Sir, Sorry for your disappointment. However, as has been mentioned before as well, Admins on this forum lead busy lives, and are not obligated to update trains promptly or attend to questions immediately. Although they appear online, they might be busy with other things.
This unfortunately results in some inefficiency in this site, but it cannot be helped. This site does sometimes contain stale/wrong info - people correct it when they find time. As Pradeep mentioned, train numbers themselves are not sufficient. Dates need to be looked into and researched. Usually, News Articles are the best source of such special train info since they provide dates of run as well - the same can thereafter be promptly updated on this site....
more... With the new enhanced News section, you can now cite a "News Entry#" to direct members to specific News Postings.
@Admins: Your contribution is greatly appreciated. But please do take care of your other day-to-day priorities before attending to this site. This is still a casual/recreational site, and it should not be adding to your daily stresses. It is well-understood that this site is not perfect, and such imperfections will always be present.
Thanks a lot.
