DCC Locomotives, Signal Lights and Track Problems

Leon asks you for comments on track problems:

"I am running DCC. Several of my engines run rough, (stop go) and I cannot find the problem. Do your readers have any suggestions?"

Don asks:

"How can I get my DCC Diesel locomotive to 'see' a signal and activate it when it approaches? Also vice versa, after the train passes turn the signal off?"

Gordon has a DCC question too:

"What should one look for when buying DCC for the first time? My N layout needs 5 Controllers and 84 turnouts and is to be expanded very soon. With that in mind is DCC likely to be expensive?"
