That Join is missing at least two bolts, one track clamp and there's the one bolt just bouncing.  It also look as if at least one tie plate is cracked.  This joint needs work before it gets worse.

Nothing wrong with that joint, at least by north American standards. It is common practice for railways in North America to only use 2 fasteners per tie plate, and as long as there isn't several ties in a row with loose fasteners the track will stay in gauge.  Many railways in my area only wish their track was this good. ;)

slow operate relays or train detector receivers with a safety feature (a delay after receiving a valid input signal) to manage it.
