== History == The IRE service was first introduced in the 2001 summer timetable, due to the increasing abolition of Interregio routes by DB's long-distance division (DB Fernverkehr). As a result, several German states ordered InterRegioExpress trains on the routes affected. In addition IRE trains were also introduced on routes that had not previously had an Interregio service (e. g. on the Stuttgart–Tübingen–Aulendorf and Ulm–Aalen routes).
