More roof details for the Siemens S70 HO model

More roof details for the HO scale model of the Siemens S70 LRV: corrugated sheeting in the center part, cable channels on both sides left and right. 

B-end in front, A-end behind, with
junction box, Thermo King, APS (on the B-end only), propulsion container and brake resistor. 

Simplified for HO scale, but modeled as fine as 3D printing allows
