Launch Freight Carts onto your Freight Track grid by placing into hoppers adjacent to a Depot.
TIP: Change the allowed cart types at Freight Cart Stations to restrict use of lower tier carts to allow higher tier versions to automatically replace slower carts in active use. The higher speed carts will enter active service as soon as the slower ones have returned to a depot after the restriction is applied.
