muffluvin Posted November 8, 2017 (edited) My kid wanted a trolley for his Lego City. I am into 4-studs wide cars and modular mocs, no idea how to begin this en devour. After a few failed attempts, I turned to this section of the forum. I found Solitary Dark's MOC of the San Francisco Trolley. His MOC was the basis for the chassis on this one. This is made out of bricks we have on hand. I plan to make modifications to the cabin, the windows make it look more like a boat than a trolley. My boy's tall order was to motorized the MOC. I manage to squeeze in the Power Functions I.R. into the cabin. The battery pack can also be mounted but it would stick out of the cabin. So I modified this one to run on 9v rechargeable Lithium Ion battery. I stumbled on a number of threads in this section regarding this topic so I went ahead and soldered one end of a PF cable to a connector for a 9v battery I made the thing modular for easy access to the PF components. It also makes changing the appearance of the train easy. Hope you guys like it, like I said, this is my first attempt. Appreciate all the contents in this forum. Here are more pictures: Here's a short video of the Trolley on the move. Edited November 14, 2017 by muffluvin grammar and spelling Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted November 9, 2017 What a great MOC ...simply loveful! The PF motor and the receiver are the icing on the cake! Share this post Link to post Share on other sites
zephyr1934 Posted November 9, 2017 What a great MOC, small motorized builds are always tricky but you made it look easy. If that really is your first train hopefully your boy will pull you in to the deep end (grin) Share this post Link to post Share on other sites

Hiding the PF components was the first order of the build. So a week was spent figuring out the perfect chassis. Like I said, one can fit a Lego PF 88000 or a 8878 in there but it would come out of the cabin by a stud. I did made a longer cabin but the proportions were off so I decided to make the battery mod instead. This is indeed my first train build but we do have the Lego Cargo and Winter Holiday trains.

McWaffel Posted November 11, 2017 Do you have any pictures of how you placed the batteries inside? And how you modified them? Share this post Link to post Share on other sites
muffluvin Posted November 11, 2017 (edited) @McWaffel AskUncleDavecom on youtube has a great video guide on the topic Images of the Battery Placement and Cable Edited November 11, 2017 by muffluvin spelling Share this post Link to post Share on other sites
McWaffel Posted November 11, 2017 That's pretty cool! Much cheaper alternative to the official Lego stuff... Maybe that's something I could power the Christmas train with! I hate the battery pack in the tender... Share this post Link to post Share on other sites
muffluvin Posted November 11, 2017 (edited) Yeah, definitely cheaper than Lego PF's lithium ion battery box. You can get a 4 pack of rechargeable 9v batteries + 4-bay charger for cheap on amazon. In the Winter Train, I expanded the tender by 4 studs to accomodate both IR module and battery box. Edited November 11, 2017 by muffluvin spelling Share this post Link to post Share on other sites
Man with a hat Posted November 12, 2017 Nice trolley. At first I wondered why there were so few windows. Apparently to hide the PF. It is nice and clever build. Share this post Link to post Share on other sites
