Powering PF motors without batteries?

Hi all

 

Back in January I was looking at getting a Lego train set, and creating my own, very small layout (on my living room floor which has spare space of about (but no more than) 5ft by 5ft).

I still haven't achieved that goal yet but I'm looking at doing so again and I'm wondering, given the existence of the old 12v and 9v train sets, is it possible to power the PF trains without using batteries?

If so is it an expensive way of doing things?

Thanks in advance.

Your best best bet would be to do this.

This tutorial would be helpful for one who wants to turn a PF train motor into a 9V train motor. Otherwise, you would want a electrified third rail which would stud onto the center of your train track and then have a device that would attach underneath your train which would pickup the current from the third rail. You would then simply plug the train motor into the device that contacts the third rail and voilà! That is... I assume it would work. :grin:

You could swap the motorized wheel section with a 9V version, use 9V track and power controller (you don't necessarily have to do electrical mods like above). The track and 9V components are all rather expensive. For example this kit would get you started: http://www.ebay.com/itm/Lego-9v-Train-Controller-and-Track-2867-and-2865-/162593042317

I think a decent rechargeable battery solution like Panasonic Eneloop makes more sense. You can get a good kit with more than enough AA batteries for one engine and a charger for about $35.

Yes, you can power PF trains without batteries.  You would have to make some sort of power pickup from metal tracks and/or overhead catenary.  It would be more expensive since you don't already have 9V or 12V tracks and parts and starting from scratch.
