July 29 2014: IndiaTechOnline Special:
The  mobile and the Internet has  come to the rescue of Indian  rail travelers, who for decades have endured  bad food service at stations and on the train from  government-run monopolies..
Half a dozen enterprising outfits, countrywide have   stepped in to provide  hot, clean meals and snacks at railway stations -- based on the passenger's choice and online booking. All it takes is prior booking at their website, with your name, train and PNR number -- and where you want the food delivered. They do the rest... networking with restaurants and hotels all over India to  serve you from the nearest one.  The menus are extensive and cover all tastes -- veg, non veg, jain, western, diabetic...  the meal is brought to your seat.  Typical cost of a mini meal is Rs 100.

In recent weeks the media has  focussed on these new passenger -- and Net-- friendly services. We provide links to the latest news stories which provide fuller details:
"Log in, meals ready!" July 20 2014: Times of India
'Berth’ of new food service for train passengers", July 28 2014: Financial Express

We also  provide below a checklist of the services cited in these articles
