The record table

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

How this table is compiled

The middle half of the table runs from 0.17 km to 0.74 km, and that band is where most of the engineering on this page actually sits. Between the longest and the tenth-longest the drop is 0.8 km, which is the part of the table that changes when a single scheme opens.

Where one of these 6 lengths disagrees with an operator's own figure for Poland, the table keeps the published value and notes the difference instead of averaging the two. The 6 rows for Poland are ordered by length, not by date, so the 2009 opening sits well down the table without being any less current.

Lengths for Poland are recorded in metres which is how the operators publish them and why the shortest entry here reads as 130 m and not a rounded figure. The longest entry is 7.2 times the shortest and 2.2 times the median, which is the quickest measure of how uneven the table is.

Dates for Poland refer to opening to traffic, not breakthrough, so the 1954 entry was under construction for some years before that. Laid end to end the entries on this page would run 2.77 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The dated entries carry 4 distinct opening years across 55 years, and the median opening year is 2006. Read down the length (m) column, the 10 values run from 130 m to 2 500 m with a midpoint at 804 m; the spread rather than the maximum is what says how uneven this set is.

Reading the figures

After the 2000s the next busiest decade here is the 1950s with 1 openings, so the building effort came in more than one wave. Only 4 of the 10 rows carry anything in the prov. column, so that field describes a minority of this table and the rest of the rows are recorded without it.

The table below lists 10 entries with a recorded length, each giving a name, a length in metres and, where documented, the year of opening. A new scheme in Poland would have to beat 0.93 km to change the head of this table, and that is the figure worth rechecking when one opens.

The entries sum to roughly 2.77 km of bore, an average of about 0.46 km each, though that average describes no actual row. The tunnel column names 10 distinct entries on this page, Kopiec Kosciuszki and Lubon Maly among them, each traceable to the operator or administration record it was taken from.

Second and third place go to Laliki at 0.68 km and Dworcovy at 0.19 km. 10 of the 10 rows carry an entry in the notes column — 100 per cent of the table — and that column is where the qualifications live: tube counts, closures, boundaries and the reason a figure reads the way it does.

Tunnel building in Poland is shaped by geology and settlement pattern as much as by transport policy. A tunnel list for Poland reads differently from a neighbouring country's: 0 of these 6 structures pass three kilometres, and the same journey time is bought with one long bore in one country and a dozen short ones in another.
