Tunnel Reference Sources: Railway History and Directories

This page is the railway history and directories section of a reference list kept with this archive since the late 1990s. It gathers 22 entries — 14 external references and 8 pointers into the record tables held here. Every external address on this page was re-checked against its own content before publication, not merely for a response code.

A destination that now serves a parked domain, a default server page or an unrelated site was dropped without replacement, because a link like that is worse than no link. The original list was far longer. Two decades of link rot removed most of it, and what remains is the part that still resolves where it always did.

Descriptions are the compiler's own, carried over from the original entry and left in their original wording where they still describe the destination. Where an entry points into this archive rather than out of it, the target is one of the record tables and opens in the same window. No entry here is a paid placement, an exchange or an affiliate arrangement; the list is what one compiler found useful while assembling the tables.

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

How this archive is compiled

A reference list on a subject like this ages in a particular way: the operators and administrations outlast the enthusiast pages, and the material that was hardest to find is usually the first to disappear. National road and rail administrations tend to keep their material at stable addresses for years, while project sites are taken down once the structure they document has opened.

That asymmetry is visible in what survived here, and it is the reason an almanac should record the figure itself rather than only point at where the figure was published. Anything that could not be corroborated at the time it was compiled was left out of the tables, whatever the reference list said about it.

The tables in this archive are the authority for the numbers; this page is the trail of where they were checked, not a substitute for them. Where a destination has moved to a new address under the same owner, the entry follows it only if the new address serves the same material.

Entries are listed in the order the original page listed them, which groups them roughly by subject rather than by country or by date. Nothing on this page is generated from a feed or a directory service; every line was entered by hand and has been checked by hand. A destination that answers but has changed subject counts as gone for this purpose, because the entry would send a reader somewhere the description does not describe.

The distinction that matters on a reference page is between a source that can still be consulted and one that merely still responds, and only the first kind is listed. Readers who need a figure rather than a source will find the tables faster from the record pages linked below than from any of the external entries here.

Questions about this record

How many of the original links survive?

Of the entries on this page, 14 external addresses still answer at the exact path they were listed under. The rest were removed. The original reference list dates from the late 1990s, and most of what it pointed at has since moved or gone.

Why were dead links removed rather than pointed at an archive copy?

Because a reference is only useful if it resolves to the material it claims to. Where the destination no longer exists at its own address the entry is dropped, which keeps the list honest about what can still be consulted.

Are these links endorsements?

No. They are a working compiler's list of places where tunnel figures could be checked. Nothing here was paid for, exchanged or solicited, and inclusion says only that the material was useful when the tables were assembled.

What do the internal entries point to?

The record tables kept in this archive — the road, railway, subaqueous, canal, highest and oldest lists, and the per-country inventories behind them. They are listed alongside the external references because the original page did.
