Module 2 , 2016 paper attempt

[PJW]

Hi All,

I attempted the question 1-a of 2016 paper.It asked the minimum braking distance for passenger and freight train.Now passenger train and freight train runs at speed of 120Km/h with acceleration/de-acceleration of 0.8 m/s and 100 Km/Hr with ace./de-ace. rate of 0.5m/s.

After calculation they give me braking distance as follows:- passenger rains 695 meters and freight train 773 meters.

Do I need to consider 773 meter as D(distance between consecutive stop signal for my answer to question 1.b??

Regards

I haven't checked your maths, but yes you must ensure that a driver of any train gets enough distance to brake from the highest speed that they are authorised to travel.  What is your doubt?

Hi,

I just added my calculations find the attached and kindly make your comments.

Currently I have a lot to do on many fronts, so whereas I'll eventually get around to it doubt whether it'll be in next week- hopefully someone else will step in!
