One of the slowest trains on this route. Takes the longest to cover GKP-LJN via main route. Heck, some trains taking the longer loop line are faster than this train. Since both BJU-GWL and LJN ICE run back to back, pax only deboard after GKP. Hence, getting a local ticket and finding a seat is very easy.
On the DN side, this train usually runs ahead of GKP ICE and makes sure that the ICE will reach GKP some time late since overtakes usually doesn't happen.
