Very very true. I guess they have to build one before relizing its a bad idea…..
8km/h top speed and 400 tons of top mass. For comparison a TGV POS (that is the lighest TGV train) is 415 ton gross mass and its only 200 meters long.that is, quite a bit shorter than the span of the bridge.
its also quite obvius playing bridge builder that it kindof not a good idea
