To the possible solutions to this problem…..
1. the best possible solution would be introduction of sky trains…..m joking…its true that the chances of derailment of sky trains are next to zero….but then to match the needs n infrastructure its impossible….so its rejected outright…
2. we can use a sensor to detect possible faults in a track….fit it on the engine…and preempt any accidents…but if there are any faults the information shud be relayed back to the engine at least 1000 m before the particular spot…why…simply because the breaking distance for a Pulsar 220 with dual disc brakes and weighing 150 kg needs at least 18 m to come down from 60-0 kmph ….now translate to that for a fully loaded train…and u can calculate the figures…now the placement of these sensors would be next to impossible on non electrified tracks on account of needs for individual ower units and controlling..…but on electrified routes, there’s a possible hope…suppose we mount a master sensor at the station and individual slave units at points of each electric pole…say drawing power from them too…may be we an do something…I hope a vague idea is forming…today technology exists even for communication through electric lines…so controlling those devices shouldn’t be problem…
3. Another possible thing that can be down is to introduce ridge on either sides of the locomotive wheels…the extra support may jus do the trick …but again that would require modification to tracks at points of crossovers…a real headache…also possible pros and cons of this approach need to studied..
So I believe that the sensor is the only feasible solution in sight..now the sensor should provide the following info…
1. Misalignment if any along the tracks
2. Change in level of the rails, say an unusual dip or rise which can cause an unusual force of the wheels and may cause disorientation and disbalance.
3. unusually long gaps between tracks at joints
but all this is worth scrap if the attitude of railway officials remain the same, the careless ‘chalta hai ‘ attitude is the actual cause of all the accidents. At most places the tracks have preserved to the state how the British left them half a century ago…virtually untouched.
Just a plain look in the more accident prone sectors reveal they occur mostly as result of neglect and lack of timely and proper maintenance works on the tracks.

Herculean Task
I owe this to an ol school buddy of mine. He considers me some sort of a genius when it comes to providing causes and solutions to problems that he brings forward to me…I have been often accused of been over caring of my friends so here is what I thought of his present problem. He studies in some institute of India where only gods are supposed to enter and there they gave him this thing to do. Poor Guy, his situation similar to that Hercules in Heaven…he has to prove himself to the existing Gods that he too belongs to that place….so here his Herculean task
Thematika: - Problem 1

30 injured as train derails near Kanpur
Nearly 30 people were injured, five critically, when the Kanpur-bound 2308 Jodhpur-
Howrah Express derailed.
Railway sources said the accident could have been caused due to some problem on the
track.
http://ushome.rediff.com/news/2007/jun/12derail.htm
AP: 3 killed, 21 hurt in train derailment
Three passengers were killed and 21 others injured when 14 coaches of the Nagercoil-
Howrah express derailed near Duwada village in Visakhapatnam district late Monday
night, disrupting rail services in the region.
Several other trains were cancelled due to the mishap.
Since the time the wheels rolled on the rails, derailment has taken thousands of lives.
Brainstorm on the cause-analysis and remedial measures for derailment of train
Now we must have all observed that trains wheels have a ridge along the inner periphery. It may seem innocuous but it has an important function I believe, it is what enables the train to turn and balance it on the tracks. Most guys must have realized by now that trains don’t have any steering wheels, so how it is able to negotiate turns. Simply the ridge rubs along the track and the resistance to the friction gives a slight push to the wheel which enables the coach to turn when several wheels on the same side of the coach feel the resistance or push in tandem. This is the same feature that enables train from shifting from one track to another.
Now for derailments to happen two major triggers must happen, 1, the force or push is enormous enough to push the carriage of the track or 2. There s a fault on the track line either misalignment with joining rails or too long a gap for the wheel to skip safely

M back.....
First of all I’m sorry coz of long absence which resulted in this blog to seem like orphaned and abandoned. If I go on to the reasons for the same…yeah there are reasons to this…perfect reasons…..m having a job now…well that’s jus not an excuse…u may think, but it is. Again, I started this blog out of sheer inspiration from Vishnu, a college buddy of mine and a fellow Gunners (for the ignorant , that’s English for Arsenal FC) fans. His blogs have been superb pieces of English literature, though the Bookers keep eluding him time and over….it was he who literally pulled me in…and my only aim was to match his witty, tongue in cheek take on the things that kept happening around him. Then there was my favourite jackass of all times, the evergreen Walker (though Ashish is what his good ol parents prefer to have him called). What’s special about him is, he so like me…and I think that should be more than enough compliment for him.
Now why I got lazy in the middle overs….simply because the above two guys stopped too. I was left with no more competition…Vishnu went on to join TCS…well I too was supposed to join him there had IBM not lured me in…and he seems to have no time for his blogs cant blame him. As for Walker, the poor old chap has been unlucky to the state that he he has gone into a sabbatical mode….he refers to this state of his as ”Not Available”…and curiously enough his last blog was about him getting the feeling of becoming invisible…..
I sincerely apologize to my innumerable fans whose numbers I cant count on my fingers ( guess negatives and zeros are not finger dependable)…for having kept them waiting for so long…
Guess I begin again…
