Railway and Locomotive Engineering, October 1898

The “James Toleman” was developed by Frederick Charles Winby to test the installation of a long firebox between uncoupled axles. Each axle had its own power plant, with the inner cylinders driving the first driving axle. Thus one could do without long coupling rods. The boiler was oval in cross-section to fit between it large wheels. After attending the Columbian Exposition, she was given to the Milwaukee Road for trials. However, it quickly became apparent that she repeatedly had too little steam and parts regularly broke. Even a lengthy visit by Winby to the USA could not solve the problems that had arisen.
