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

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
