Hydraulic Switch Construction Photos

The Mount Washington Cog Railway automatic hydraulic switch at Waumbek is completed. The first automatic switch was installed at Waumbek in the spring of 2003. Al LaPrade - the designer of the switches at both Marshfield Base and Waumbek - designed another new switch and supervised the installation at Waumbek.
