The second bridge over the Wombat Creek has caused me a lot of thoughts. Firstly getting the right hight above the railway line. It is possible to clear the top of the steam locomotives by just 2 mm, but I think it is too tight. With a slightly higher bridge there are inclines on both sides leading up to the bridge. Not a problem for the trams to climb.
Secondly the plate girders are from a Peco kit. I have used the middle parts for the first bridge over the Creek. The remaining parts are glue together to form two girders. They are just too short for the span without relaying the railway track. If the bridge is narrower the girders are fine, but that will result in another issue.
How to get two tram tracks across. A gauntlet with fully ‘intertwined’ tracks would be an interesting feature, but with the inclines and a curved tracks I have opted out of this solution. Instead the tracks will just clear the girders and be very close to each other. Two trams may not be able to pass the bridge at the same time. A fact, which gives me a reason to install working traffic lights. I’ll keep you posted!
