Bogie Exchange - Variable Gauge Axles

Variable Gauge Axles

Variable Gauge Axles also called Automatic Track Gauge Changeover System is a newer and faster development than bogie exchange. While Bogie Exchange is "obvious" and brute force, VGA / ATGCS is "subtle, hidden" and elegant. The SUW 2000 ATGCS requires a change over track about 20 m long, with a shed if there is snow compared to a small marshalling yard required by bogie exchange.
