Amazing ALT Hydraulic elevator @ Stockholm Central station, new track 19 Upper

Just listen to the hydraulic pump! it sounds beutiful! But it´s more loud than i expected... i thougth it would be an silent one. like many other modern hydraulic elevators are in sweden... I also like the sound it gives when i press the buttons... only 3 more known elevators (all of Midroc electro elevators in sandviken and in gävle) have that feature... I want to find out who is behind the controller system. (it´s not P DAHL, for sure.) Fun facts: ALT=Advenced Lift Tecnology (Founded in 1994 as an rest of the old DEVE elevators in Alvesta, their hydraulics have same construction as DEVE, like this one...)
