Bristol Parkway time-lapse

From 2018, here's a time-lapse featuring a tandem lift of two 40m gantries near Bristol Parkway Station. 

It formed part of the electrification of the London to Cardiff rail route.

We find that the combination of Hi-Res stationary cameras (mounted on masts or available infrastructure) and off-the shelf time-lapse cameras (fixed to moving vehicles or cranes) compliment each other nicely. 

The latter are smaller, less fragile and easily/quickly attached to vehicles when little time is available for installation and the former, higher quality ones, provide a solid foundation for a top class result.
