Industrial Rail Trolley Car Project

I just began a project to modify and restore to running condition at least 1 of 3 Industrial Rail trolley cars I have on the deadline track at the car-barn. Since there is no assembly diagrams and electronics functional information available for the Industrial Rail trolley car, I will document & share step by step what I do to disassemble and modify these cars. Attached is my project description and disassembly instructions. If anyone has some functional info to contribute, please share it in this post.

Interesting project! Wish I had your info a few years back. I have several IR trolleys, and my first broke down after a year or so, requiring the heroic efforts of the MarxMotorMan, Bob Testa, to transplant a replacement motor and/or gearing to get it running again. It has run flawlessly since then on my el line:

I have expanded my project plan considerably since my first post. The bigger plan is attached. I have learned a lot since dismantling Car 1106.

Bob,  very interesting project, I really liked your detailed breakdown.  I have a IR trolley that’s still working.  Mine seems to have an electronic E unit as well as the bump-n-go feature.  I didn’t see where you mentioned a E unit in yours.

Hi Boomer! I do not posses a significant knowledge of electronics, but I think the electronic E-Unit is the combination of the HEF4011B NAND IC that does switching via "and or logic," & the HEF4027BP Flip-Flop IC. If my guess is correct, there are 2 ways of reversing the trolley. One is the bump-&-go mechanical method that employs the micro-switches, and the other is via the electronic flip-flop IC. I will edit my project description if the above guess is found to be right by somebody with smarts in electronics. Boomer, thanks for making me aware of the electronic E-Unit.
