This idea is to offer human powered “rail bike” rides on unused railway lines such as the E&N Railway line. This service would be a fun way to experience the outdoors and get physical exercise. A company called Rail Explorers on the east coast of the US offers a service like this and they might be willing to sell their ride bikes. You can learn more about them here: http://www.railexplorers.net/index.html
Funders would received blocks of tickets to ride on the “rail bikes” once the service is up and running.
This project idea depends on obtaining approval from the owners of the dormant or closed railway.
