@duffandrew Thanks!

Very intelligent construction. I also had the idea of using mindstorms to manage Lego model railroad. But I did not have time/money/room. I will do this in the future.
Some suggestion for improvement: Instead, that NXT sends power to servo motors, which manipulate a switcher, use the NXT to send power directly to the track. To do this, use the Lego article 8528. Then you can use the NXT for manipulating speed, too.
No switcher and speed regulator will be needed.

How much would this cost assuming I have the trains but not the NXT items?

@WowOmgStudios
It's hard to say because this is a collection that I built up over time. I would guess it is worth about 2 thousand if I bought all the parts today.

Love this! What sets should I get to get this done?

Thanks. I posted the details of the components I used on a site called mocpages, Youtube won't let me post the exact link here but if you go to that site and search for train automation you will find the details.

Yes everything is custom built.

Was programming it hard?
MrTrainfanatic 1 year ago
No, the programming was not hard. Basically it is just a loop that continuously checks the light sensor readings. If the light intensity spikes (because the train moves in front of the sensor) then the power is cut to the tracks (by turning the servo motor). After a delay (while the train is stopped at the station) the power is restored and the train moves on.
