POST#1 shows an automotive 12 volt battery!! Nobody runs a train on a 12 volt automotive battery!! The first mention of a train is in post #11. NOTHING ABOUT A TRAIN WAS MENTIONED UNTIL POST 11, so don't be telling us it was obvious and we missed it. OK?"The train"
Obviously this is for a train. How could you all have missed it? And if "automatic operation" needs to be explained to you...
Are there no longer any internet experts whose free answers are worth the priceless time to ask an incomplete question? I would have a talk with the manager if I were you. This is ridiculous.
At least one of us can't identify sarcasm in text. It might be me.POST#1 shows an automotive 12 volt battery!! Nobody runs a train on a 12 volt automotive battery!!

Yes, that's an accurate decryption of my sarcasm. This thread reminds me of questions and assignments I've been given by bad bosses. They make very vague, foolish comments or suggestions and then somehow immediately make you look the fool for not understanding. They put you on the defensive, scrambling to recover by begging more silly details about their silly plans as if making their dreams come true is what you were born to do. OP could be any of the people in this room except Anderson:So why didn't the TS tell us what was really wanted back at post #1? Automaticly reversing a motor could be anything, from a donut-dunker to a washer machine. Most of the responding folks here are not mind readers, unable to instantly perceive details from some cryptic statement.
AND, the train motion has been completely worked out in a long thread some time ago, all the way to initiating the slowdown to stopping perfectly. so if somebody able to search through the threads can find it the TS can have a complete answer.
AND, note that the picture in post #1, with a 12 volt automotive battery, is not even remotely similar to how model trains are driven. Nobody launches them with 12 volts and unlimited current.
You didn’t give away anything. There are several commercial and open source products which do exactly that. Control a model train from a cell phone.The trains (trolley's) I've seen are far more sophisticated than simply having a switch to change direction. The last train show I attended had this very thing in several exhibits where a trolly would - um - trolly from one end of town to the other. Stop for a minute then go back to the other end. Had to be some more sophisticated setup than just some switches. Maybe a proximity switch or hall effect transistor to sense the presence of the train and its location as well as direction of travel. Command the train to slow and stop. Then after a set period of time reverse direction. I wouldn't think I'd want to be slamming a model train locomotive from forward to reverse in an instant. Likelihood the train would derail.
Lots of great train setups at the exhibit. Very impressed. Makes me want to take up the hobby. I played with electric trains and race car sets when I was a kid. Today's kids don't want to know anything about something they have to assemble and operate. If it doesn't have an ap they aren't interested in it.
HEY! MAYBE WE SHOULD DESIGN A TRAIN THAT CAN BE RUN FROM A CELL PHONE.
Awe geez! Just gave away another million dollar idea. Yeah, I could have hit delete. Oh well.
