A true-to-life mock-up of a Swedish metro train is created in just ten weeks.
In Västerås, Sweden, a team from Voith Engineering Services meets representatives of Bombardier Transportation. Voith becomes the preferred partner for the coming decision-making process, thanks to its skills in railway technology and expertise in the construction of mock-ups. But also for practical reasons: Voith has affiliated companies on location and can promise delivery of the mock-up to Sweden and its installation on-site.

Kick-off in Chemnitz. The project manager, Andreas Silvan, presents the job to the team. It is clear to all present-the timeline is ambitious, speed and flexibility are the order of the day. Communication is crux. From now on, weekly coordination meetings are held with the Bombardier design team. This allows a rapid response to the suggestions and requests of the client.

The engineers at the Voith prototype center must react flexibly to changes in the scope of the project. From the original five-meter mid-section that was originally planned, the project now calls for almost nine meters and the interior and exterior cladding and driver’s cabin and console have yet to be added, not to mention a simplified version of the platform, which is also part of the mock-up. Voith takes the changes in its stride. Immediately, six engineers are assigned to the project instead of three.

The critical phase begins: the concepts for constructing the structural parts needed for the mock-up and chassis are drawn-up. The structural calculations are performed and design proceeds. Further sub-contractors are selected, the materials procured and the details of the manufacturing process prepared.

Manufacturing work begins on the parts. The number of welded assemblies and parts milled from wood, aluminum and steel begins to grow in Voith’s workshops. The key ingredient to the process: a high-precision 5-axis milling machine that can handle pieces as large as three by five meters.

“In addition to the engineering specifications, this project places high demands on logistics and the need to meet really tight deadlines,” says Steffen Schaarschmidt, Head of prototype construction at Voith Engineering Services. The model is prepared for transport. Make three out of one: The overall length of 19 meters necessitates breaking the mock-up into three pieces.

The pieces are loaded onto special transporters for the trip from Chemnitz via Trelleborg to Västerås, about 100 km west of Stockholm. At the same time, seven prototype experts from Voith arrive to reassemble this unique piece.

Project manager, Andreas Silvan, travels to Sweden for the official handover of the mock-up to Bombardier Transportation. In a letter to Voith, Mattias Jansson, a designer at Bombardier, is effusive in his praise: “I want to take this opportunity to tell you that I think you have done a fantastic job.”

Concept design review No. 1 in Västerås. Representatives of Stockholm’s municipal transport authority see the mock-up of their future metro train for the first time. The representatives of Bombardier’s clients are unanimous in their conclusion: “A perfect basis for the upcoming discussions and decision-making.”
