N scale modular track catenary masts

Four types of catenary masts that fit to this thing: http://www.thingiverse.com/thing:1593126

The masts called "dam" are mounted vertically in the embarkment, the masts called "track" slide under the track bed.

The "pull" masts mimic line tensioning masts, in this case with internal weights.

**Please note** that the height of the catenary matches model railroad standards. That means if you use the masts as decoration on an electrified model railroad, you mustn't extend any pantographs or they will collide with the catenary supports.
