The next time you are on board C-3 coach of the Panchvati Express, abstain from playing cards or chewing tobacco. If you do so, then be prepared to receive an earful from your fellow passengers. After all, you would be travelling in the 'Adarsh Coach' that has found a place in the 'Limca Book of Records' for being the first of its kind. What makes this coach, which allows entry only to monthly season ticket (MST) holders, is the fact that all of its passengers follow a voluntary code of conduct that includes prohibition on consumption of liquor, chewing tobacco and playing cards. Travellers are also expected to adhere to cleanliness guidelines and switch off lights during daytime, among others.
