Elevated tracks for rolling stock maintenance New measurement track for the ICE engineering workshops in Munich
DB Fernverkehr AG
DB Fernverkehr AG is a subsidiary of Deutsche Bahn. It is a mobility provider of long-distance transport services with a focus on product and service quality to ensure comfortable and reliable operations for passengers. DB Fernverkehr AG provides national and international long-distance services on daily scheduled services. To this end, it operates a dense network of over 800 daily long-distance rail links in Germany.
When it is time for an inspection, the entire ICE train is driven into the 450 metre-long workshop where it is serviced on three levels simultaneously: beneath the train, at boarding height and in the roof zone. Adjustment work on the railcar bodies is now carried out on the new 200 metre-long measurement track that was installed in November 2018 and which is also suitable for the new ICE4 models. This meant rebuilding the old test track. The aim was to create an absolutely flat railtrack with a height tolerance of less than 0.5 millimetres. The precise adjustment work needed between the railcar body and the bogie can only be undertaken when you have an absolutely level track.
There are eight workshops in Germany to ensure that the 230 ICEs of Deutsche Bahn are inspected in a correspondingly close network. In the ICE workshop in Munich, the deflection of the tracks had to be reduced to the minimum required for measuring tracks according to DIN 27202-10. When surveying the existing tracks, it was found that twice as many props were required as before.
However, the resulting reduction in the prop spacing interfered with the existing ventilation technology for the 200 metre-long working pit beneath the track. A particular challenge for which Blumenbecker Technik had a special solution ready. For another Deutsche Bahn project, Blumenbecker Technik had already developed props that could effectively absorb the resonance generated by the trains while at the same time directing used air out of the pit. The supports, which are similar in appearance to a child‘s plaything, were soon dubbed “jumping jacks.”
In October 2018, 102 new props, 71 of which were jumping jacks, were assembled on site in Munich, and the old tracks were relaid and configured. Subsequently, the calibration was carried out in cooperation with the calibration centre of Deutsche Bahn. After a rebuild time of just four weeks the first high-speed train could be run onto the new test track for an inspection. The test track was finally put into servicen one day earlier than planned.
With this project, Blumenbecker Technik was able to demonstrate its many years of experience and expertise in railway technology. The possibility of converting existing tracks instead of buying new ones was a major cost saving for Deutsche Bahn.
The short conversion time of just four weeks also contributed to this. Particularly noteworthy is that the new „Jumping Jack“ prop development can also be used for other railway projects.

» We are very happy about the fast and smooth Improvement of the measurement track, as each unused track costs us a lot of money. «
