Ohrenstein and Koppel 50 hp like locomotive for OS-Railway with wormwheel gear transmission

thingiverse

When I created this thing the objective was to use a worm wheel transmission with a N20 motor on a train. The victim this time was the Ohrenstein and Koppel 50 hp locomotive. Base of the design were some drawings of the locomotive. The design is for use 32 mm gauge. I have never seen such a locomotive live so in the design will undoubtly be flaws. When I look to the video I see that there are differences between the drawings and real live. The plan is after covid to have a look at the museum. ( see https://stoomtreinkatwijkleiden.nl/) Further the steam driven parts (pistons and connecting rods) are not realized. You can see the train in real live in action here: https://www.youtube.com/watch?v=6ORvIHaZZ1k For the motor I used a N20 6V 500 rpm motor. The locomotive is not very fast. I am waiting (customs,mail and so) on 1000 rpm motors to see if that gives more speed. The batteries used are 14650 Li ion batteries.
