It's going to be necessary to gear up between the motor and worm somehow - if you don't, the locomotive will be incredibly slow. I actually used a worm drive in my Lego B6, with a gear ratio of 4.8:1, it's very slow. The setup you have above is 24:1, about 5 times slower than my B6. Here's a Lego gear ratio calculator, the closer you get to about 1:1 the better: http://gears.sariel.pl/
