This is one of my first posts over here, but have been messing about with lego trains for a little while now. This one is my first serious project and is at a point where it's very nearly complete.
It started out as a plan just to build the #4534 Lego Express engine & tender from parts I had handy - which I was able to do with a good result and few subbed parts. From then my wife egged me on to MOC it, so it got some xmas lights sprinkled around it... and I build my first motorised train car! The motor also pulled power from the 9V train engine which was fine on a small track, but on the longer runs that I do with BLTG it had some issues and the motor stalled a fair bit - just couldn't draw enough power on certain parts of the track. I tried a few things with a newer PF motor as well and it was better than previous, but still no dice.
Just in the last couple of weeks I started another car, plus the plan to incorporate a battery box into the build so that neither motor was reliant on the 9v tracks. Again the 2nd car was a challenge (trying to fit it all inside a 6-wide car was the big issue) but after about the 3rd rebuild I got it working to a point i'm 95% happy! Due to the gearing being quite exposed and hard to cover I decided to turn it into an attraction and threw in windows in one side so show off the main gear and the technic axle that drives the santa sled. Figured it's a good point as it's a show train - but usually shown at model train shows rather than lego ones so people are always curious about how stuff works.
Last to the party was the power supply, it's not pretty but it works :) Inside is a 6xAA battery box loaded with eneloops and this powers both motors happily. I did try the 9V monorail battery boxes but I don't have any decent 9V batteries handy and the cheap one died very quickly - though I can change this later if it does turn out to work. At this point I also added a second train motor to the engine, as the battery box is heavy!! Now pulling 2 full size cars and a couple of smaller cars too it's a reasonably long train.
The train is strictly 6-wide, though that's about the only rule I kept :) Height wise it should run the usual BLTG display (just needs to clear the overpass on the #7937 Train Station) but you won't find any technical train stuff here :P this one is purely for fun :D
Anyway, enough with the boring stuff... some piccies!
And the fun part :) (though sorry about the quality of video - I know it's BAD - I will replace when I can)
My future plans are to test with better 9V batteries and if possible sub in a couple of these, which should reduce the overall size of the power car. Also, going to evaluate if I can change the base of the last car to red instead of black to match the rest of the train better. Limitation at the moment being that LEGO never made a red base in that style - so it'd look a little weird.
Let me know what you think!
