In order to keep the train traffic on the section to a standstill for as short a time as possible, the rock blasting related to the renovation had to be carried out carefully and as quickly as possible. Project started: May 2010 Project ended: Midsummer 2010 Project scope: 5,000 solid cubic meters in a single blast During the renovation of the Neulamäki railway tunnel, we blasted approximately 5,000 solid cubic meters of rock in a single blast. At the same time, we guaranteed that train traffic will be at a standstill of less than 48 hours at the renovation site. It took a total of about a month to prepare for the blast and prepare for the h-moment. After the blasting, the work on the site was carried out with the accuracy of a stopwatch to ensure uninterrupted traffic. Also check out a video of the blast taken during the 2010 nightless night .
