Description:Equipment purchased in 2017 as part of ongoing efforts to improve VLA infrastructure. The machine is much bigger and better than the original equipment used to lay ties in 1976, adding a level of automation to the removal and insertion of cross-ties not previously available at NRAO. Now one machine will remove an old tie from under the rail, remove a new tie from the stack and properly position it, and then insert it under the rail, thus speeding the process considerably. The goal is to replace 5,000 ties per year. [show more]
