HPS, Johanna and Telvar 50 for Pasing railway station

What is behind these abbreviations?

HPS is the abbreviation for Hering-Portal-System also known by the Deutschen Bahn AG as "platform roof type Bodenheim”. Johanna is the locomotive from the Walthelm company and Telvar 50 is the 50 tonne railway crane from the Hering Gleis- und Ingenieurbau company. The Telvar 50 and Johanna are just what’s needed at Pasing railway station, as well as a number of other special purpose machines and vehicles, in order to be able to realise the largest railway platform roof assignment in the history of Hering. After a one year planning and production phase, the two roofs measuring 155 x 9.20 m, were preassembled before the gates of Munich, and each roof was then respectively loaded on 27 railway carriages.

After mounting the supports with the aid of road rail excavators, one of which is operated in track construction and civil engineering, it was the time of truth on Friday the 23rd of October, 2009, at 20:00 p.m.: Railway crane Telvar 50 and the carriages were pulled into Pasing railway station by Johanna. This marked the beginning of a suspenseful assembly project with the railway crane Telvar 50 working in double shift operation.

The assembly work required the utmost attention of all involved, particularly at night. By 05:00 a.m. on Monday morning, one complete side of platform roof had to be fully assembled and the other side had to be temporarily stored on the platform. The second side of platform roof was mounted during the week in a single shift operation. Though faced with a number of challenging obstacles, such as lateral braces and wiring, as well as lengthwise running overhead contact wires, the assembly ran smoothly and on schedule, thanks to our well-practiced assembly crew team and our railway crane drivers. The second railway platform roof was assembled just as smoothly 14 days later. After the main assembly was carried out, the glazing, sheet metal forming and electrical work was performed so that we had practically finished working on both of the roofs before Christmas.
