Hi, I wonder if anyone can help with a loud banging noise that happens when a train passes.
We have 4 lines apparently all uni lines. On one of the lines only, when a train passes, we have a short 5 seconds of "ta dum ta dum "noise. Apologies for poor explanation. I have a short video where you can hear this noise at the end. Its obviously at a certain point, does it ever time a train passes on that line in that direction. No other train makes this noise.
Would appreciate any answers please
