Hi all, some days ago I was watching some videos of LGB G-Gauge trains running in the garden. They're big and very well done...and really out of budget for me. So I wondered if I could replicate such a big locomotive using Lego. And trying to be cheap!!! A big train like that needs: an XXL PF Motor; a simple PF battery box; a PF receiver; a PF remote control. All in all we're at about 50 Euros from Lego Shop. 4 large flanged wheels from Lego or BBB (3 Euros each - 12 Euros) - our total increases to, let's say, 65 euros. Then, it's time to think about a body - it must be as simple as possible, sturdy, and without too many special parts. Since I was not particularly inspired (in these days I'm playing a lot with the new Lego Boost set) , I used a well known Lego model. Yes, it is what is seems - a 7720 multiplied by 2 - 32 studs long, 12 studs wide. Even the Voltage is doubled . This was painted blue, otherwise the two red "lights" would disappear. Since track is now quite small - I chose to draw only one central buffer, suggesting this is a narrow gauge model. As you can see it is simple as it can be. I think I can try to stay below the 100 euros limit. Then, this weekend I began to prepare the mock-up to test how heavy it could be, if everything fits inside and so on. Here below you can see the yet unfinished 7720 on steroids . In this photo I used a 45mm track from G-gauge - it is actually a part of LGB track. This big girl will be able to travel on both tracks. Reasoning in studs, the L-gauge puts 4 studs between the wheels, while the G-gauge requires exactly 5 studs. Since wheels will be mounted internally respect to the fake suspensions, both gauges can be achieved by adding or removing two half Technic bushes between the wheels (one per side, so 4 studs + 0.5 stud + 0.5 stud =5 studs). But we want to be cheap - and LGB track are not - so we'll keep the standard Lego track. You cannot see it from the photos, but the black part is all made by 3x2 and 4x2 parts - too small - but I had only those around. Inter-axle is 15 studs - BBB wheels can handle the R40 radius, but this is an heavy locomotive, so I think I'll shorten the inter-axle to 13 studs. Now I'm studying how to transmit power to the wheels - I was tempted to use a chain-driven system based on lego 3711 parts, but it costs a lot and I'm not sure how much weight and torque it can handle. I'll end using the Lego 32702 gears - they seem right and are cheap enough. Let's see how this develops!!! I personally am very curious to see it in action! Ciao! Davide
