Luas extensions — Finglas, Lucan, Poolbeg, how a tram line is consented, and what the register shows at the Cherrywood end

Within 2 km of the Green Line terminus at Cherrywood, the register holds 225 planning applications lodged in the 24 months to 12 September 2026, with 124 of the 152 decided granted, 102 commencement notices and 30 appeals. Cherrywood is what a Luas line does to a register over fifteen years: the tram arrived in 2010, the strategic development zone followed, and the applications have not stopped. The next lines — Finglas, Lucan, Poolbeg — will do the same thing to other places, and the process they go through is the one this guide sets out.

From strategy to railway order

A Luas extension starts as a line on the NTA's Greater Dublin Area Transport Strategy 2022–2042, which names Luas Finglas, Luas Lucan and Luas Poolbeg among the light-rail projects for the period, with capacity works on the Green Line. Transport Infrastructure Ireland then designs it through option selection and non-statutory public consultations — the route choices, the stop locations, the depot site — before applying to An Coimisiún Pleanála (formerly An Bord Pleanála) for a railway order under section 37 of the Transport (Railway Infrastructure) Act 2001.

The order is the consent. It authorises construction and operation, confers compulsory acquisition of the land in its schedule, and sets the conditions. The Commission publishes the application, takes written submissions, holds an oral hearing under section 41, and decides. There is no appeal; section 47 allows eight weeks for judicial review. It is the same instrument that consented MetroLink and DART+ West, and the guides on those cover the mechanics.

Where the three extensions stand

Luas Finglas runs about 4 km from the Green Line's Broombridge terminus through Tolka Valley Park to Charlestown, with four stops. TII lodged the railway order application in 2024, and the Commission's case page is the only reliable statement of where it is. Luas Lucan — Lucan through Ballyowen and Liffey Valley to the city — and Luas Poolbeg are at design and consultation stage, with the route options published by TII and no application yet. Our reading: the non-statutory consultation is where a stop moves 200 m; the railway order hearing is where it does not.

The works that keep an existing line running go through the ordinary register. South Dublin County Council granted permission on 23 July 2026 for two new maintenance lanes at the Red Cow Luas depot on the Naas Road (SD26A/0127W), an application with the same five-week observation window as a house extension. Stop upgrades, park-and-ride changes and substation works appear the same way.

What a neighbour can do

On a line with a live application, the written submission and the oral hearing are the statutory windows, and a submission from a residents' association counts as much as an objection from a landowner in the acquisition schedule. Before the application, TII's consultations are where the route is still open. After the order, the remaining matters are compensation for land taken under the Acquisition of Land (Assessment of Compensation) Act 1919, and the order's construction conditions on hours, noise and vibration. A tram line is shallower and closer than a metro tunnel; the vibration condition is the one to read.

The eight-week judicial review window under section 47 closes the statutory process. The 2024 Planning and Development Act, once its judicial review provisions are commenced, will tie standing more closely to having made a submission, which is another reason to make one.

What a tram does to the register: Cherrywood

The Green Line reached Brides Glen in October 2010. The Cherrywood strategic development zone planning scheme was approved in 2014, and the register around the terminus has carried a large scheme every year since. In the last two years the point 2 km around the town centre has seen 225 applications, more than 100 commencement notices, and — because Cherrywood is a strategic development zone — decisions that cannot be appealed to the Commission where they comply with the scheme, which keeps the appeal count low for the volume.

Two applications lodged on 30 July 2026 show the scheme still filling in: 32 residential units at Bishop Street, Laughanstown (DZ26A/0580/WEB) and 40 at Castle Street (DZ26A/0579/WEB), both in Development Area 7, both due a decision by 23 September 2026. The Finglas line will produce the same pattern at Charlestown, and the Lucan line at Ballyowen; the register is where it shows first.

Frequently asked questions

Is Luas Finglas approved?

TII lodged the railway order application with An Coimisiún Pleanála in 2024. The Commission's case page and luasfinglas.ie carry the current status; we do not hold or estimate a decision date.

How do I object to a Luas extension?

Through a written submission during the railway order application's notice period, and at the oral hearing. Before the application, TII's non-statutory consultations take comments on route options. After the order, judicial review must be sought within eight weeks under section 47 of the 2001 Act.

Does a Luas line appear on the planning register?

The line itself does not; it is consented by a railway order. Works to an existing line — depot extensions, stop upgrades, substations — are ordinary planning applications, such as the Red Cow depot lanes granted by South Dublin in July 2026.

Will a Luas stop near my house need planning permission for higher-density housing?

Not by itself, but the development plan and any strategic development zone scheme around a stop allow higher densities and lower parking, and the register around Cherrywood shows what that produces over a decade.

The Cherrywood explainer reads the register around the terminus in detail; the MetroLink guide explains the railway order. See the applications around the Green Line's end in the Explorer at Cherrywood, or open the Killiney-Shankill place page and the Dún Laoghaire-Rathdown place page.
