These drawings were the starting point for reconstructing the bogies in 3D, and are now part of the construction drawing library I setup in the Fusion Team Hub for this project. A large part of the technical drawings of this renovation have been preserved, especially for the Y32 bogies. In the renovation, the original bogies were replaced by Y32 bogies, and a Faiveley AM56 pantograph was mounted on the roof as well as a dome with a TV camera in it to record the behavior of the pantograph. The original P 7918 postal vehicle was built in 1952 at Allan in Rotterdam. The CTO measurement vehicle is a former postal vehicle that was converted in the 1980s into a measurement vehicle for the Center for Technical Research (CTO). Because of their importance in railway engineering, we decided that the CTO bogies needed to be modeled in detail and by part, to provide a solid foundation for both engineering calculations and a range of educational realtime 3D visualization options. Usually, two bogies are fitted to each carriage or wagon, one at each end. A bogie provides some of the most essential functions to the rail vehicle: It carries the load, it transmits the traction and braking forces, it guides the train in a safe manner and it smooths out track irregularities. In essence a bogie is a metal frame to which the axles and wheels are attached. ![]() And although the models aren’t completely finished yet, I will show the current status here and explain how I got there. I started modeling the bogies of the CTO measurement train late 2017, between the first and second scan session. ![]()
