LEGO Train 12 Volts Posted February 19, 2012 I was a little bit skeptical about this project, but after seeing the video with train running fast with the piston rods still on I have dreamed of a new diesel shunter, like the 7760, in the PF era I look forward to your updates...

SavaTheAggie Posted February 19, 2012 A very thorough video. I don't know if I've seen this design attached directly to wheels on motors, but it's not the first time I've seen those crankshafts used on small wheels to create pushrods. Looks much better on 8-wide models. Texas State Railroad Engine #1 by SavaTheAggie, on Flickr --Tony Share this post Link to post Share on other sites
LEGO Train 12 Volts Posted February 19, 2012 (edited) Wow Tony, you always have great knowledge! On the 8 wide model the rod looks good... brickon Konrad! Edited February 20, 2012 by LEGO Train 12 Volts Share this post Link to post Share on other sites

I am thinking technic flex style pushrods and trimmed cranks so it does not stick out 2 studs! Share this post Link to post Share on other sites

DaddyDeuce Posted February 23, 2012 (edited) Here you go guys! Proof of theory! Just wanted to say "good job". By coincidence I was trying to come up with something similar last week, but the parts you've identified are a much better path.
