Stadler’s Weinfelden commissioning hall targets 2028 operation

Stadler’s 210-metre commissioning hall in Weinfelden is expected to begin operating in the first half of 2028, supported by an adjacent 750-metre electrified track installation.

The project has moved beyond planning, but the announcement gives no construction cost, annual train throughput or phased delivery schedule. Those omissions limit assessment of both the capacity gain and the risk to the 2028 target.

Why does Stadler need another commissioning centre?

Stadler has begun construction at a new commissioning facility in nearby Weinfelden, Switzerland, after its existing centre in Erlen approached capacity limits. The company reports that increased productivity at its Swiss manufacturing sites has placed pressure on Erlen, while available land restricts further expansion there.

Commissioning covers the work that follows vehicle assembly. Before a new train enters trials on the public railway network, its electrical, mechanical and control systems must undergo commissioning and functional testing.

Stadler currently carries out much of this work at Erlen, in the canton of Thurgau. The company says higher output at its assembly plants has created demand for more downstream testing space, turning production gains into a constraint at the commissioning stage.

The Weinfelden project is intended to add capacity without relocating existing production activities. That preserves Stadler’s production footprint but requires another site to handle final vehicle preparation before mainline testing.

Relieving this constraint could reduce delays between assembly and public-network trials, although the company has not quantified how many vehicles are currently held up or how much time the new site would save.

What will the new site contain?

The project’s main structure is a 210-metre-long hall measuring 35 metres wide and 16 metres high. It will have four indoor tracks and one outdoor track.

Additional areas will support final assembly work, painting, storage and technical staff. The scope places the site across several post-assembly functions rather than limiting it to static electrical checks.

An adjacent electrified track installation will have a combined length of 750 metres. Newly assembled rolling stock can use these tracks for first powered movements and functional checks before proceeding to further testing on the public railway network.

The track installation is about 3.6 times the length of the hall, quantifying the extent of the powered-test area relative to the covered commissioning space.

Stadler describes the new centre as additional capacity rather than a replacement for Erlen. The announcement does not state how work will be divided between the two sites, so the operating benefit cannot yet be translated into a firm number of additional trains per year.

When will construction and hiring happen?\

Construction officially began on 3 November, and the new centre is close to Stadler’s headquarters and manufacturing activities in Bussnang. The announcement does not specify the year of that November start, so readers cannot establish from it how the construction milestone relates to the June 2026 land approval.

Stadler expects operations to begin in the first half of 2028. That target depends on delivery of the hall, its four indoor tracks and one outdoor track, and the adjacent electrified installation.

The company expects the project to create around 80 jobs, primarily for commissioning electricians and automation specialists. This is a workforce forecast, and the estimate does not provide a hiring timetable or an occupational split beyond those two fields.

How was land for the tracks secured?

Stadler needed additional land for the track installation. On 11 June 2026, Weinfelden’s municipal parliament approved the sale of approximately 3,963 square metres along Brunnenwiesenstrasse to Stadler Rail Schweiz.

The acquisition enabled Stadler to proceed with the planned test tracks. The municipal decision represents a completed project step, unlike the projected 2028 operating date and 80-job estimate.

What is not yet demonstrated?

The announcement provides no capital value, train-volume forecast or detailed timetable for the transition from construction to testing. It also does not identify how much Erlen activity will transfer to Weinfelden or whether staffing at the older centre will change.

No rail operator, customer or specific rolling-stock programme is linked to the project. The announcement therefore cannot show when vehicles for any named service will reach commissioning or how the additional space will change fleet delivery schedules.

Stadler has reported the capacity pressure, obtained municipal approval for the land and started construction. Its expectation that the new centre will ease the commissioning constraint and support about 80 jobs remains forward-looking until operations begin.

The first test will be whether the 210-metre hall and 750-metre track system open on schedule and demonstrate enough additional throughput to absorb work generated by higher output at the Swiss plants. Until then, the first-half 2028 date and job forecast remain company projections.
