The record table

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

How this table is compiled

The three longest entries alone account for 16.56 km of the 81.47 km on this page, which is 20 per cent of the total from 3 of 99 rows. The shorter half of the table totals 12.63 km against 68.85 km for the longer half, from the same number of rows.

Where one of these 99 lengths disagrees with an operator's own figure for Croatia, the table keeps the published value and notes the difference instead of averaging the two. The 99 rows for Croatia are ordered by length, not by date, so the 2013 opening sits well down the table without being any less current.

Lengths for Croatia are recorded in metres which is how the operators publish them and why the shortest entry here reads as 50 m and not a rounded figure. The longest entry is 116.4 times the shortest and 11.8 times the median, which is the quickest measure of how uneven the table is.

A new scheme in Croatia would have to beat 5.82 km to change the head of this table, and that is the figure worth rechecking when one opens. Eighth on the list is Tuhobic at 2.14 km, which is where the table stops being about record holders and starts being about ordinary infrastructure.

Second and third place go to Sveti Rok at 5.68 km and Ucka at 5.06 km. The table on this page runs to 128 rows and records Tunnel, Length (m), Date of opening, Reg. and Prov. for each of them, which is the shape the original compiler chose rather than one imposed here.

Reading the figures

Dated entries run from 1980 to 2013, and the busiest decade is the 2000s with 48 recorded openings. Read down the length (m) column, the 128 values run from 50 m to 5 821 m with a midpoint at 576 m; the spread rather than the maximum is what says how uneven this set is.

3 of the 99 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 81.47 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The dated entries carry 14 distinct opening years across 33 years, and the median opening year is 2006. The material on this page is held in 52 captions rather than in running text, 419 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Roughly 63 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. The captions name 49 distinct places and structures — Ploce, Gora and Maslenica among them — and those names are the index into the length tables where each is recorded with its own figure.

The earliest dated entry is Ucka, opened in 1981, and the most recent is Sveti Ilija in 2011. They are not uniform: the fullest runs to 19 words and the briefest to 6, and on a page of this kind the long ones are where the explanation lives — the caption carries what the picture cannot.
