Maintenance of Siemens ER20
When the ER20, a diesel locomotive of the Eurorunner family produced by Siemens, joined Slovenske železnice’s locomotive fleet back in 2014, we were tasked with delivering the maintenance in order to support diesel traction services operated by Slovenske železnice’s freight division SŽ – Tovorni promet. Although the unit, which was under lease by SŽ, was sold two years later, there was still a notable demand for this type of maintenance because such locomotives are commonly owned or leased by operators on Slovenia’s and Croatia’s rail network.
Our experience in servicing Taurus U4 locomotives, which are also built by Siemens, gave us some head start with this new challenge. The part which sets ER20 apart from Taurus is most notably the way maintenance is scheduled – while electric units are serviced according to mileage, diesel locomotives such as ER20 record the number of hours in service to determine their maintenance periods.
In 2014 our teams from Ljubljana and Maribor depots received hands-on training by MRCE how to carry out ER20 inspections – these are done on completing 500 hours in service (referred to as ‘W2’) – and completed their first such inspection without assistance in August 2014. Later on we completed the training for ER20 overhauls done at 2,000 hours in service (W4) at our partnered depot, and are now officially certified for Eurorunner maintenance up to Level W4.
At present, the majority of periodic inspections on Eurorunner locomotives is done for Adria Transport and LTE. We also deliver light repairs (not included in periodic inspections) under arrangement with the owner, as appropriate.
