2004 Track Circuit Calculations

[Peter]

Hi,

Thank you for the feedback.

I appreciate your mentorship and analysing the condition of the Relay end resistor is quite a good idea. I will do that and get back with the result.

I have a doubt regarding the feed end resistor.

Can the margin of 20% be included in every track circuit calculation, initially before starting the calculations?

Please help.

Regards,

Jenni

My approach tends to be to work out the critical number and then comment, rounding the number to something sensible. 20% is arbitrary and you can argue for more or less. The important thing is to understand the magnitude - ie don't suggest a tiny fraction and don't suggest something that is too big. Get comfortable with what is a reasonable value and put words down to support that.
