Lego Trains 'Click Clack' noise around the track help?

Hi all i have just gotten into Lego 9v trains ( usually have the Pf trains) and while driving the train around the track i noticed when the train went through the intersection piece of track it made a loud "Click Clack' noise as each carriage rolled over it. & it sounded very cool like a real train "Click & Clacking' over track.
I now want that 'Click Clack' noise over my entire track

Is there a way to do this? maybe putting tiles around the exposed studs of the track so the train wheels have something to bump against to make a noise?
Or maybe modding the actual train wheels boogies? (not sure what there called)
Or just  have a train layout that is all crossovers lol:legoheadbang:

Anyways hope someone has some advice or answers as to if the "Click Clack" noise can be reproduced around a layout
Thanks

SnapLock,

The closest I have come to replicating the noise of the old steam trains is by using the old push-along wagons from the 70s.

You know; the ones with the blue and red magnets.

When they go over 9V track, the axles rattle on every join of track.

It is music to my ears.

Thanks for the info Brickie
