Questions that I need answered (by train pros)

I am not so sure you would want to bump up Gordon to 9 volts although Ucwepn may be able to shed more light on the idea. 9 volt may be too fast especially on a smaller layout with many curves. He may not hold on to the curves and fly off and if your mod Gordon is on an elevated table could spell disaster if he fly's to the floor. If its just a bump up in speed you are after maybe a boost to 3 volt (2 AA or AAA batteries) or 4.5 (3 AA or AAA Batteries). Another option would be to leave it as 1.5 volt and install a Power Dash motor or the like which would require less modification. All should give Gordon a good boost in speed. I thought Ucwepn had a 9 volt Gordon video but I can't seem to find

That actually wasn't ucwepns mod, he did 4.5 V mod. I tested him out with 9V he runs fine on the layout as he has a broken or misplaced gear in his motor and I can't find out which one. And in turn slows him down JUST enough to make the turns ok. It isn't permament either, so I can run him at 1.5V at will or 9V. MIght try 10.5V but that might blow up the motor insanely quick. So I'm going to stick with 9V for now. And thanks Tomy fan!!!
