These mid sections are based on a tried-and-tested type, they are 25 metres long, they consist of two parts connected by a joint and bellows, they have three bogies – two of them powered by engines – and six axles. They boast 48 seats and 136 standing places. One significant difference to the “U5” base models in use: They have no driver’s cabs. Instead, they can extend the “U5-50” models to 75 or 100 metres, respectively. A 75-metre-long train thus offers 140 seats and 432 standing places, while a 100-metre-long train provides 186 seats and 580 standing places. These trains can be walked through their entire length and offer passengers a completely new feeling of space and travel.
The single greatest advantage: With longer trains, VGF is able to significantly increase service and capacity on individual lines and routes without having to deploy additional trains, place a further strain on line utilisation or make structural adjustments at stations or in workshops.
