I’m offering a repair service for Duplo battery trains 2961 & 2961b. If your train no longer works I will check it and if possible repair it. My charges are £5 to check a train and if repairable plus £15 to repair, or if not repairable plus £30 to provide a working replacement. Your original train will be returned. (Return postage of £3 in original order). I will send contact details once a repair has been purchased.
