Switchback Railway Tower Designs

Rather than sticking to the usual switchback railway towers I thought I would incorporate parts of Fogg's journey into the towers instead. I have picked four different places/monuments from the book and tried to take bits of them and make them into towers. I think it would be nice to have two contrasting ones to really show the progression of Fogg's journey while on the railway. I like the idea of having Charing Cross Station (#1) as the tower at the beginning of the ride to show the start of Fogg's journey and then this would also be contrasting to the oriental tower.

Out of the oriental towers I think #2 or #4 would work best.
