Mittnabotåget is/was a regional train service connecting Trondheim in Norway with Sundsvall in Sweden. It includes trains operated by Veolia Transport on the Mittlinjen between Sundsvall and Östersund in Sweden, and Norges Statsbaner’s cross-border Nabotåget services from Östersund on to Trondheim in Norway.
The line between Trondheim and Östersund operates using BM92 diesel multiple units, with two daily departures each way. The line operated by Veolia in Sweden uses electrical Regina units. In Östersund and Sundsvall, connections are available onwards towards Gävle and by local trains and X 2000 expresses.
Mittnabotåget is partially financed through funds from the European Union.
In autumn 2012 there was a change. The regional transit authority Norrtåg took over the responsibility from the Swedish state. This concerned the trains on the Swedish line Östersund - Sundsvall. The operator changed to Botniatåg, and from that time the X62 trains that Norrtåg owns are used. The trains to Trondheim are still the BM92 operated by NSB. The name Mittnabotåget was discarded, and instead Norrtåg and NSB is used.
