What does tunnelled mean?
Tunnelled is the British past tense and past participle of tunnel, a verb meaning to make or travel through an underground passage. It can describe the construction process, as when engineers tunnel through rock or beneath a river, or movement through an existing passage, as when a train tunnels across a mountain. The word also has a figurative use for concentrating narrowly on one issue or outcome. Tunnelled is common in technical, engineering, transport, and news contexts, while its metaphorical use often suggests limited perspective or single-minded attention. In American English, “tunneled” is the more usual spelling, although “tunnelled” is also understood. The form is especially associated with British English and should not be confused with “funnelled,” which refers to passing material through a funnel or concentrating it into a narrow channel. Its literal sense vividly evokes digging through solid ground, making it useful whenever an account needs to emphasize hidden infrastructure or purposeful movement beneath an obstacle.
To make a passage through earth, rock, or another obstacle, or to travel through a tunnel or enclosed passage.
"The railway tunnel passes through the ridge, and the train tunnelled out of sight within seconds."
The double-l spelling is standard in British English; American English more commonly uses “tunneled.”
Having been made or excavated as a tunnel or underground passage.
"Passengers waited in the tunnelled station while the train approached."
This participial use normally occurs before a noun and is especially associated with transport and infrastructure.
Sometimes a route is not built over the landscape—it is tunnelled straight through it.

Where does tunnelled come from?
Tunnelled is the British inflection of tunnel. Tunnel entered Middle English through Old French tonnel, ultimately derived from Latin tonna, meaning a large cask; the word originally referred to a passage resembling a barrel. The English tun belongs to the same Latin-derived family and preserves the related idea of a large cask.
