Are there layouts where the locomotive is automatically activated to whistle approaching a road crossing?
If so, how is it done?

Lionel allows you to do with with Legacy and the sensor tracks now. As for pre-sensor track days it is possible. You;d have to have an isolated block before the crossing and use a relay or IR sensor to know when the locomotive enters the block, and then have circuitry that sends the signals to blow the whistle/horn. The only problem is that you can only run the train one way through the crossing or else it'd signal after the crossing when coming from the other direction.
Dale,
Neat approach-thank you
Down the road, will give it a try
Need I say that Dale is an amazing electronic master mind.
Thanks again for all of your patients and help that you have given me.
