VLA Antenna Transporter peddles by a telescope

There are over 40 miles of double tracks stretched throughout the VLA for these transporters. These massive machines can gently lift and carry these 230-ton antennas around the array with ease. The antennas’ distances from each other are changed several times a year to change the VLA’s eye on the sky. Each one cycles into and out of the Antenna Assembly Building for routine servicing over the course of several years.
