Railway students on field trip

Friday 31 Mar 17

Railway Design and Maintenance

Railway Design and Maintenance is a course at the MSc programme Transport & Logistics - the study line Railway Management and Engineering. The purpose of the course is to achieve competences within the field of design and maintenance of railways – this includes track and traction current.

It is also possible to follow the course as continuing education. Read more here

The DTU-course Railway Design and Maintenance has a tradition of spending a day each spring visiting railway sites. This year the field trip took place Wednesday March 29. 

First stop of the day was Dybbølsbro station in Copenhagen. Catenary expert and teacher Russell Hankey pointed out to the students the different catenary assets at the station. Dybbølsbro is a good place to do this because it is possible to get close from both the bridge and the platform - without the need of safety equipment. And both the S-line and the regional trains go through there (see photos 1 and 2).

Catenary Surveillance Centre

After Dybbølsbro the students continued to OCK - the Catenary Surveillance Centre operated by Banedanmark (RailNet Denmark). The centre monitors both the S-lines and the regional lines - however, from two different centres and thereby two different systems, but both located at the same address.

The students had a short introduction to the two centres followed by a guided tour among the many colourful screens. Jon Link from OCK explained the procedures for the many daily maintenance activities, where planned interruptions are needed. And he also explained the procedure for the unforeseen activities on the lines - e.g. in cases where the catenary is demolished by accident (see photo 3 and 4). 

Brøndby - visiting the New Line Copenhagen-Ringsted

From OCK at Otto Busses Vej in Copenhagen to Brøndby and the New Line Copenhagen-Ringsted. At the premises in Brøndby the New Line has an Info Centre, which is open once a month to the public. Or by request. At the Info Centre onewill find a small exhibition with archaeological findings from the project sites. The exhibition also includes information on the nature protection at the new line. 

Berit Jendal from the New Line Copenhagen-Ringsted gave the students a broad introduction to the project - both the economic and planning aspects of the project as well as technical challenges and solutions. Afterwards Steffen Bach presented the extensive work with 3D. From the very early tender phase until now where the project is finishing the track laying, it has been mandatory to use 3D visualization(se foto 5 ovenfor). This is the first time that this has been done in such a consistent manner in Banedanmark. The advantages and the disadvantages were discussed.

Site visit - Køge North station and the Kulbane tunnel in Valby

The first site visit of the afternoon was at Køge North station. At the time of the visit there was no work conducted there - the tracks were laid, and the next steep is catenary and signalling. These works are to be completed by the Electrification and the Signalling Programme. 

The students accessed the site from the walk and cycle bridge at the south of the station (see photo 7). From there they could see that the construction of the platforms was ongoing. However, there still remain quite a lot of work before the awarded station will be in place (see photo 6). 

Going from Køge North station back to Copenhagen, the group passed the M4-bridge, crossing two motorways. Unusual for such a large construction, the bridge was built while keeping the traffic open. The motorways were closed only for two weekends during the construction.

The last stop on the trip was back in Copenhagen - in Valby. The Kulbane tunnel. The site is a 700 metre long tunnel and this work is also coming to an end. The tracks are laid while catenary and signalling remains. On this last site the students were equiped with safety wear to visit the tunnel (see photo 8 to 9).  


The New Line Copenhagen-Ringsted

From 2010 Banedanmark (RailNet Denmark) is constructing a new dual track railway between Copenhagen and Ringsted via Køge. This will offer a better timetable with more departures, shorter travel times and fewer delays. The budget is DKK 10.4 billion and the line is due to open in 2018.  The line is designed to handle speeds of up to 250 km/h for passenger trains and is Denmark's first railway for high speed trains.
