AB=AC
AD=AD –-----> ABD≈CAD
BD=DC
BA=AC
A1=A2 -------->BAE≈CAE
AE=AE
BD=DC
D1=D2 -------->BDE≈CDE
DE=DE
so if BDE≈CDE AE and BC are perpendicular.

You never gave the speed of the blue train.
The path to collision is equal to 1½ circles.
1.5 x 210 meters
= 315 meters
I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute.
315 / 35 = 9 minutes
Answer:
9 minutes
