The two lateral control desks (use depending on the location of the signals), give the possibility to use the locos in pushed operations. In this case an acoustic signal is used by the trains. Of course there's a control desk in the middle of the cab for driving forward. Adtranz uses modular mechanical, electrical and pneumatic systems and an efficiently diagnostic system for lower maintenance costs. The locomotives have additionally two little pantographs on the sides for use under the loading facility. Because of the loading gauge the locomotives were brought from the Adtranz factory without the cab extensions.
