Hello everyone,

I am trying to calculate GEBR and braking curve

The safe braking model is the method used to determine the minimum separation between trains. IEEE 1474.1 defines it as:

“An analytical representation of a train’s performance while decelerating to a complete stop, allowing for a combination of worst-case influencing factors and failure scenarios. A CBTC equipped train will stop in a distance equal to or less than that guaranteed by the safe braking model.” (IEEE CBTC standard 1474.1, section 3.1)

That’s a mouth full.

Translation: the safe braking model is the calculated distance to stop a train, under the worst-case failure, without colliding with an obstacle in front.

Which static dynamic train parameters to use?

What do I need to pay attention to when calculating?

How do I test?

Thank you.
