Old and New Long Steel Track

In "Cranes on Tokyo Monorail Track Switching Work", there are four cranes working. They are replacing concrete tracks. There are also two steel tracks to be removed, and one steel track to be installed. They are not handled by the cranes.

 

See the four orange machines standing under the old brown steel track. They are jacks. The steel track will be jacked up and moved sideways until it will not interfere with the new track. When it is put aside, transporters bring the new track onto the support.
