How to power trains these days?

Got myself the Lego Horizon Express thanks to Bricklink and now I’d like to power it. I also would like to power an Orient Express set. Thing is the train motor on the Lego website has been out of stock for quite a while now. Are they planning to update their powered stuff? What are the new solutions these days? submitted by /u/LightHawkLive [link] [comments]
