I have started work on another Bridge for my LEGO Railway layout, but this time I have built a Dual Track (Line), Double-Leaf Bascule Railway Bridge. This does mean I will need to build yet another baseboard to house it on, but I have received a large heap of LEGO Train Track, so all should be fine.

A Bascule Bridge (commonly referred to as a drawbridge) is a movable bridge with a counterweight that continuously balances a span, or “leaf”, throughout its upward swing to provide clearance for boat traffic. It may be single or double leafed.

Movable Vertical-Lift-Span Bridges have a movable portion deck which remains horizontal as it is lifted vertically. The amount of headroom available is determined by the variations between water levels and the heights of the lift towers. Water traffic beneath these bridges are usually restricted to low-masted craft, barges and tugs.
