Narrow Gauge
Indian Railways - the Backbone of Indian Transport System
Indian Railways has always remained the backbone of Indian transport system. Since its inception during the British regime, the Railways been the main public transporting system in India. Owing to the supreme significance of the Indian Railway in the mobility of the large population of this vast stretch of land, it has been aptly said that to discover the bewitchingly diverse patterns of Indian cultural mosaic, one need only to make a railway journey across the length and breadth of India. That much is the commutation of the citizenry of India in this mode of transportation. The Indian Rail transport is the most commonly used long distance transportation system in the country. The network has a total length of over 63,140km (39,200 miles). One of the busiest and heaviest carriers of the world, the Indian Railways carries over 5 billion passengers and 350 million tones of freight in a year.
While standing as the backbone of the Indian transport system, The Railways runs on three categories of tracks – Broad Gauge, Meter gauge and Narrow Gauge. Among these three kinds of gauges, the Broad Gauge is the most prevalent type of track. It is 1,676 mm (5.5 ft) wide and about 86,526 km of track under the Indian Railway network runs on this type of track. In some locations where Broad Gauge in not feasible, Meter Gauge is being used. However, that covers only very less length of the railway network. Again, Narrow Gauge is present at very few locations, especially in hilly stretches. It covers around 3,651 km and is mainly used in the Nilgiris and Darjeeling stretches. Concerted arrangements are in progress for the implementation of the Unigauge project to convert all tracks in to Broad Gauge. The zoos in India also use Narrow Gauge and such tracks are also maintained by the Indian Railways.
There can be no doubt that the backbone of the Indian transport is the Indian Railways. It is a mammoth transportation system having multifaceted aspects. Out of a length of over 63,028 km, 16,000 km of track has been electrified. Passenger accommodation of the Indian Railways falls in to various categories. The categories are: a) 1A First Class AC; 2) 2A AC Two Tier; c) 3A AC Three Tier; d) CC AC Chair Car; e) 2S Seater Class; and f) G General. Indian Railways has Bholu as its mascot. Again, trains are categorized in terms of speed, number of stops, fare-structure, etc. The express trains are identified by a four-digit number. The first two digits indicate the zone and the division respectively and the last two are the serial number of the train.

should I use a narrowband fuel ratio gauge on my bike or a wideband?
I looking at adding a air fuel ratio gauge to my bike as a tuning aid.
I am not a very technical person so what kind of gauge and sensor system should I buy. I would like to just monitor the af ratio while riding and at idle. I really don't need to hook anything up to my computer or non-sense like that. will a narrow band work accurately on a fuel injected bike?
would this work for my bike?

I have a powercommander 3 I just want something to help me fine tune it being that there is no map for the mods I have and I am constantly adding mods so I don't want to keep paying for dyno time. I'm just looking for something to let me know that I'm not to rich or lean and avoid engine failure till I get to the point when I am not adding anything and will get it dyno tuned.
A narrow band is just what it sounds like. It can only read a very narrow band of the AFR range. 14.7 is the theoretical ideal ratio for gas. Its not for sure where you get the most MPG and its certainly not where you get the most power. A narrow band can tell you if you are at 14.7 or if you are high or low. It cant tell you how high or how low. Narrow bands are cheap. Some single wire sensors are only $20 and there are plans on the net to build a simple circuit with a rich / lean / good light as well as some complete kits that do the same thing. If you think this is all you need then go for it. I had one for a while on a car but did not find it that useful. I wanted to get my acceleration and power dialed in and for that you want to be operating in the rich range and have to know how rich you are. Wide bands are much more complex and therefore much more expensive. The sensors themselves are more in the $75-200 range and then you need some sort of a controller to interpret the signals and translate them into something that makes sense to you or your fuel system. About as cheap as I have seen diy kits is $150ish. Nicer ready to go kits are more starting at $250. For a bike you would want something rugged and compact.
