Consistency and transparency replace boundaries and hurdles –
thanks to industrial PLC technology with integrated standards from
the web and IT world.
One of 8 tunnel caverns. The railway technology is housed in
the air-conditioned stainless steel containers.
One of 104 cross tubes. Up to 15 switching cabinets can be
found in each cross tube.

The railway company does not just want lean
technology but also wants to become a lean
company itself
On 23 March 2011, Saia-Burgess Controls had the
opportunity of welcoming the entire management
of BLS Netz AG (including the board of directors) to
Murten. The main reason for the visit was not the
Lötschberg Base Tunnel project but the visitors were
principally interested in Saia-Burgess’s electronics
manufacturing and the lean methods used. The top
management of the second largest railway company
in Switzerland is seeking inspiration from a medium-
sized industrial company that is perceived by all
levels at BLS (including the very highest) as innova-
tive, creative and reliable.
We received the following letter from one member of
the management board after the visit:
Many thanks for the extremely interesting tour of
your company. We were very impressed by your
consistent focus on lean production and the under-
lying culture. We are still at the beginning of this
process, whereas Saia-Burgess Controls already
has crucial years of optimization behind it.
