One level crossing costs what Kavach on 321 route kilometres costs

Indian Railways approved four works on 19 September worth Rs 736.23 crore. The single most expensive item per unit is a four-lane road over bridge replacing one level crossing; the cheapest per kilometre is the train protection system.

What happened

For Prelims

For UPSC: A rare chance to compare the unit economics of different railway interventions from a single day of approvals. Use it on infrastructure prioritisation, on railway safety spending, and on Centre-State cost-sharing, where the per-kilometre arithmetic does more work in an answer than the headline figures do.
What it is NOT: The three named components of the ROB total Rs 121.83 crore against a stated project cost of Rs 133.2295 crore, and the release does not say what the remaining Rs 11.40 crore covers. It gives no completion date for any of the four works, no traffic figure for the level crossing being replaced, and no accident or SPAD data for the sections receiving Kavach or Electronic Interlocking. It does not say how much of the Lucknow Division already had Kavach, only that these are the balance sections. Nor does it state the sanctioning authority or the year of the works programme against which any of the four is booked.

Anchor
Four railway approvals were issued within an hour of each other on 19 September, totalling Rs 736.23 crore. Three of the four buy signalling or power supply, not track. The costliest single item is the removal of one level crossing, and the cheapest per kilometre is the system that stops trains from passing signals at danger.
Substantiation (data)
Kavach 4.0 on 607.7 route kilometres for Rs 252 crore works out to roughly Rs 41.5 lakh a kilometre. The traction upgrade costs about Rs 1.95 crore a route kilometre, nearly five times more. Electronic Interlocking at seven stations averages about Rs 29.9 crore each. The four-lane ROB, for one crossing, costs Rs 133.23 crore.
Comparison
Set the ROB against Kavach at its own approved rate and it buys train protection on about 321 route kilometres. That is not an argument for skipping grade separation, which removes a category of accident that no electronic system can prevent. It is an argument for being precise about what each rupee of a safety budget actually buys.
Exemplification
The Solapur approval shows how these works stack. Electronic Interlocking is being provided at seven stations on a route where Kavach, Automatic Block Signalling and Centralised Traffic Control have already been sanctioned. Modern interlocking is the precondition for the rest, so the sequence of sanctions is itself the engineering logic.
Problematisation
The ROB release lists three components adding to Rs 121.83 crore against a total of Rs 133.2295 crore, leaving Rs 11.40 crore unexplained. No completion date accompanies any of the four approvals, and no traffic or accident figure justifies any of them. Approval without a schedule is the recurring gap in this class of release.
Conclusion
A day of ordinary sanctions is more informative than a headline project, because the four items can be priced against each other. The useful sentence for an answer is that Indian Railways is buying safety cheaply per kilometre and geometry expensively per point, and that both are necessary.
