DSB’s battery chargers from our IC3 and IR4 train sets are scheduled for an overhaul service. IC3 has 96 train sets, equal to 192 battery chargers IR4 has 44 train sets, equal to 88 battery chargers Battery chargers from IC3 and IR4 train sets follow an overhaul production plan, subject for changes and extensions. It is crucial for the overhauling of IC3 batter chargers, that initial overhaul of the first battery chargers starts week 6 February 2021 as the overhaul is a part of a major overhaul service; and hence will seriously affect the overall major overhaul if the production plan is not followed. The overhaul of the battery chargers is expected to last 2-3 years according to the production plan. Besides from the overhaul service noted above, DSB also requires a framework agreement covering supply of repair service and spare parts for a period of 6 years with options for extensions of 2 x 2 years.
