A Rail Bike Tale


by Larry Da Broi
 
Having tried the hand cars that someone had built at Train Mountain, I found they were hard work and inadequate for the distances and hills of TM. Being a lifelong bicycle tourist, I was determined to build something that could be propelled using legs instead of arms (Photos 1 shows my first attempt.)
 
 
I used old bicycle parts, because I didn't know exactly what gearing would be required for the grades at Train Mountain. On the third bike I substituted a front truck for the front axle (Photo 2 shows my third bike.)
 
 
The design modification was made because, with a long wheelbase, there was a noticeable resistance when going around curves. For my fourth bike, I tried to make the frame lighter to help going up the hills. Unfortunately, the lighter bike tends to derail going through trailing switches. I also tried spring suspension on the rear wheels. The idea was to give a smoother ride, however it made the bike a little more tipsy (Photo 3.)
 
 
I just completed my fifth bike. I am trying two trucks in an effort to get a smoother ride, but I haven't had a chance to try it out (Photo 4.)


For me personally, unless I am operating a train to haul passengers or pine needles, I spend more time on the bike than on the train. These were built by the seat of my pants, with no plans. In the "second section" of this article, I will present plans and some specifications on rail bike construction.

  1. Any new renditions of your railbike? Would love to see the plans and learn from past issues.

  2. I know this has been a while, but I would be very interested in any plans, pictures, or just descriptions of what worked and what didn't. I'm sure I'm not the only one.

  3. Ivan, I'm interested in this, too. I've been inquiring at Train Mountain and it seems the bikes they had were from a member's test efforts. Reportedly, there aren't any rail bikes around as part of the club equipment. Anyone have specs on the wheels and sources? mikevdpca@aim.com
