I was a wee lad of six years old when I got 4565 Freight and Crane Railway and a 9V Transformer on Christmas morning, and I'm pretty sure I still have those same track and transformer to this day (The train itself is long gone from countless rebuilding and mocs through childhood, but I still come across the red 6x28 train plates with the 9V train logo on the sides here and there). Back then S@H was out of the question for , so for about a year I only had the loop the set came with until my birthday rolled around and I got one each of the three track types available then (Eight straights, eight curves, and two switches) and 2126. By the release of the Super Chief I had started buying my own trains, but as I was approaching my teens I started to drift away from Lego in general. The trains and the rest of my bricks went into storage for a few years when I heard about how Lego was changing to RC trains. I dove back into the hobby by grabbing both RC trains available back then (Kinda regret getting the passenger set though ) and was somewhat impressed with some of the new pieces but disliked the huge battery draining RC Battery chassis.
After that I would slowly drift back into trains with the Hobby Train, the advent of Power Functions, the Emerald Night, and currently now with the Horizon Express. I don't really buy any more track though, 9V or Plastic. I've got three sets of 9V switches and enough straights and curves that I can fit into my small abode. As said before train motors and magnets are always welcome though!
