2008 Module 2 Layout Calculation Attempt

[PJW]

You responded:

I have two questions on this reply.

1.
Required non stopping headway is 2min. I have gone for 4-aspect signalling as 3-aspect signalling exceeded 120 sec. so 4-aspect calculation is not wasted here.

2.
In stopping calculations diagram was wrong w.r.t speed as you said.
But I have shown train length on x-axis because train stops on platform with in dwell time(as the time passes for 30 sec. it’s speed is zero as I took distance instead of time it should be train length). In fact I have taken train length also for calculating extra distance travelled by a stopping train w.r.t stopping train. Am I wrong here?

Even though it is process oriented I analysed so many times for understanding the actual meaning of stopping calculations then I sent finalised calculations to you.

I stopped at the juncture of considering train length as an extra distance. No one has taken that.

Clearly I have taken acceleration, deceleration along with train length for calculating T(extra).

Why don’t you people consider train length as an extra distance?

Please answer this question.

It starts well up including calculation of the braking distances.

Hence although I have not yet had time to look into your workings, this introduction is basically telling me that you don’t quite understand and are confused.

Even if all the numbers turn out to be actually correct, this will be because you have learnt to follow a process, you can turn the handle and the mechanism spews out the desired number as a calculating machine, but from a ‘does this person really “get it” perspective’ there is evidence here that you don’t and thus you would not be getting all the marks you’d be hoping for.

Hi all,

could you please check my calculations?
Line to be covered in between pages is “Non-stopping train will cover the 1698m in 44 sec.”
