Two identical trains are moving on rails along the equator on the earth in opposite direction with same speed. Will they exert same pressure on the rails?

Question

Aaryan Panigrahi · Answer

We know Pressure = Force/Area. & Force = mass *acceleration As the two trains are Ideentical and have the same acceleration, the mass, acceleration, & the Area of contact is the same in both cases, YES. The pressure is equal in both cases!!

sneha prasad · Answer

But the solution to this question given says that since the angular speed is different thus centripetal force for both the trains will be different. I could not get this answer. Is it incorrect?
