Aplensauber? I suppose you mean "Alpenstaubsauger", right? That literally means "alps vacuum cleaner" which refers both to the origin of this loco (Austria, while this class is also used on alpine routes) and the sound of the fans.
Note: this is not an ÖBB 4010, it is a Westbahn 4010! After the ÖBB 4010 EMUs went out of service some years ago, the new Westbahn EMUs got this number.
This is obviously a DMU and not an EMU (there is no catenary, no pantograph, and the 5XXX stands for DMU in the Austrian numbering system). Unfortunately, I do not have the privileges to update the database.
