My first attempt at an Un-Specific Pacific (USP) was met with only partial success, it wasn't very fast or powerfull, it looked too toylike for my tastes and it was mechanically unreliable. The chassis and drive was basically a stretched and bastardised EN chassis and it was clearly not fit for purpose. I've been planning a v2 for a long time now, and have finally started. The XL motor is getting replaced with 2 L motors and the gearing has been simplified significantly. This has vastly improved the speed and (i think) the power to the wheels, but the has come at the expence of grip, causing not only significant wheel spin but also it to routinely pop the con rod from the leading wheels. It's powered through the centre (flangless) wheels, which drive the outer (flanged) wheels via the con rod. I did this in an effort to maximize the weight and power applied to the two flanged wheels, but that's looking like a dead end right now. Any ideas, suggestions or tips would be greatly received. Current build (tender will probably stay largely the same as the original build, although I'm toying with seeing if those little baring will make the standard Lego train wheel assembly a little less draggy). And v1 (before all the bits had arrived). Once I have it mechanically where I want it, I want to give it a smaller boiler and a more tapered cab roof, plus any and all grebelings I can think of.
