To piggyback on your question...

Are the LEDs in the car chips the same as those used in the track to sense for the digital lane changes?
Or can they be the same? I presume the function is the same, to recognize the light and send a pulse down the wire to the electronics that are attached.
MartinT and "who was it?" found some LEDs for adding to the track sensors to avoid missed pulses due to sliding.

Thanks!

Thanks, Mr. F.
Yup, that was a "duh" moment if I had thought about it. I am looking for a "sensor" to sense the LED lights on the cars to send a pulse to a circuit I am working on. Was going to use reed switches or dead/live strip, but wondered if an IR diode would work. I will Google TSOP as I am not familiar with that term.
Cheers and thanks again.

Now back to Michael's question.

PS Mr. F. Are you not at work today?
