Blocking trip
A barrier drive is according to the policy 408, the Deutsche Bahn AG defined as follows: barrier coatings or rides are small car trips , which are introduced into a track of the free section, which is locked.
Reasons for this are for example
- the elimination of the consequences of an accident or assistance, e.g. B. in the case of broken trains,
- Small car rides,
- Snow clearing drives or
- the operation of a junction on the open road.
While a normal train journey always takes place between two train stations or stops , a restricted journey can also begin or end elsewhere on the free route. The maximum speed of a restricted journey is 50 km / h, with pushed journeys 30 km / h. If there are level crossings on the driveway without technical safety devices (i.e. level crossings that are not equipped with barriers or light signals, but only with St. Andrew's crosses ), then a pushed blocked passage may only travel 20 km / h. The block can only be lifted when all blocked trips (as well as trains and train parts let in before the block) have left the blocked area again.
The train notification procedure is used for blocked journeys . If further blocked journeys are to be allowed into the blocked main track after a canceled track, the command 12 with the content "Drive on sight" must be applied to the area of the blocked main track before the next run of the first closed track. Then the second blocking trip receives a command with the same content. If there are several blocked trips in front of a signal showing "driving", the signal showing "driving" only applies to the first blocked driving.
The counterpart to the restricted trip on the Austrian Federal Railways is the side trip . A distinction is made between the NO journey (between the train station and the free route), the NM journey (between two train stations) and the SKL journey (between two or more train stations, analogous to a train journey). Since these distinctions are usually only important from an organizational point of view, with the next change in operating regulation V3 , the intention is to combine the secondary journeys into one category, which will then also be named Sperrfahrt.
