DLM AG has its origins in the former

Swiss Locomotive & Machine Works SLM

in Winterthur.

When SLM’s engineering division

was sold to Adtranz in 1998

and the workshop was renamed Sulzer Winpro,

the end of the traditional SLM was imminent.

The SLM steam team, led by Dipl. Ing. ETH Roger Waller,

decided on a management buyout (MBO)

and founded Dampflokomotiv- und Maschinenfabrik DLM AG

in mid-2000 with a share capital of CHF 650,000.

Of course, we actually wanted to continue the world-famous name SLM,

which Sulzer did not allow.

As a condition for the MBO, Sulzer demanded that we join a company.

A suitable partner was found in Hug Engineering,

a company specialising in exhaust gas purification systems.

This resulted in the initial location of DLM in Weisslingen.

At the same time as the company was founded,

the first substantial order was registered,

the overhaul and gentle modernisation of

the HG 2/3 No. 7 «Breithorn» of the former Brig-Visp-Zermatt Railway.

A small workshop was rented in Winterthur for this work.

Later both companies moved to Räterschen (Elsau).

In July 2006 the time they spent together with Hug Engineering ended.

Because exhaust gas purification systems were now mandatory,

the sale of soot filters and catalytic converters boomed.

The steam team acquired the shares of Hug Engineering and moved to Winterthur.

In Schaffhausen, it was also possible to rent the locomotive shed and the carriage works,

which were no longer needed by the Swiss Federal Railways SBB.

In mid 2020, DLM celebrated its 20th anniversary.

The planned jubilee steam journey with the 52 8055 to Chur

and on with the steam locomotive «Heidi» fell victim to the corona virus.
