How this archive measures: lengths, bores, dates and ordering

How this table is compiled

Between the longest and the tenth-longest the drop is 8.69 km, which is the part of the table that changes when a single scheme opens. Where one of these 9 lengths disagrees with an operator's own figure for India, the table keeps the published value and notes the difference instead of averaging the two.

Lengths for India are recorded in metres which is how the operators publish them and why the shortest entry here reads as 330 m and not a rounded figure. The 9 rows for India are ordered by length, not by date, so the 2020 opening sits well down the table without being any less current.

A new scheme in India would have to beat 9.02 km to change the head of this table, and that is the figure worth rechecking when one opens. The longest entry is 27.3 times the shortest and 4.9 times the median, which is the quickest measure of how uneven the table is.

2 of the 9 measured entries exceed five kilometres, and those are the ones that carry a full ventilation and escape regime. Laid end to end the entries on this page would run 25.43 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

Dated entries run from 1961 to 2020, and the busiest decade is the 2000s with 4 recorded openings. Read down the length column, the 12 values run from 330 m to 14 150 m with a midpoint at 1 750 m; the spread rather than the maximum is what says how uneven this set is.

Reading the figures

Eighth on the list is Kamshet-II at 0.36 km, which is where the table stops being about record holders and starts being about ordinary infrastructure. The date of opening column sorts these 11 rows into 6 groups, the largest being 04.2000 with 5, then PRJ with 2 and 03.10.2020 with 1.

The state column sorts these 13 rows into 3 groups, the largest being MH with 8, then JK with 3 and HP with 2. Only 4 of the 13 rows carry anything in the road column, so that field describes a minority of this table and the rest of the rows are recorded without it.

Roughly 6 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. The captions name 10 distinct places and structures — Pune, Expressway and Rohtang among them — and those names are the index into the length tables where each is recorded with its own figure.

The dated entries carry 4 distinct opening years across 59 years, and the median opening year is 2000. The material on this page is held in 6 captions rather than in running text, 67 words of it, each written against the image or row it belongs to by the compiler who put the page together.

The dated entries fall across 4 different years, which is a rough measure of whether this was a sustained programme or a handful of separate schemes. The tunnel column names 13 distinct entries on this page, Atal (Rohtang) and Z-Morh among them, each traceable to the operator or administration record it was taken from.
