Little late…. and then I thought “Better late than never”… So here’s my idea of “curve”
1. CURVE
2. CURVES

I was trying to capture both the curves ~ the train’s as well as that of the railway lines [then, I didn’t know I might be using it here :)]
I have no idea what happened to the original pic, so I’m posting the edited version 😦
If these curves are *unsatisfying*, you can always visit Alisa’s http://wheresmybackpack.com/2012/08/31/travel-theme-curves/
