Railway Braking, Tram Braking, Train Braking

Please READ MORE for the video. Braking physics related with brake shoe friction ratio (K, L etc.) and vertical force of them (to the wheel bandage or disk or rail). Brake system ensure negative force when activate and rail-wheel contact force (adhesion) must resist to brake force. So, wheel rail contact force and furthermore, vertical force of vehicle is important parameter for braking. Braking test regulation: EN13452 Some braking technologies...

Shisa Kanko, Pointing And Calling

Shisa Kanko (Pointing and Calling) Shisa Kanko (Pointing and Calling, Shisa Kakunin Kanko, Yubisashi Kosho) is a safety method to ensure “do it well in first time” or avoiding mistakes like neglect, carelessness, inattention, ignore something what it need to be sure. Shisa Kanko is about countion, eyes, looking, perception. It is essentially about Total Quality Management. We can define; Looking: Looking act perform through eyes. Seeing: Seeing...

Railway Wheel Flat

Please READ MORE for the video. Do not think that this is a new type brake, this is sample of wheel flat. If there is a small flattened spot in wheel tread, it will be bigger flat in time due to impacts on its edges...

Track and Rail and Wheel Physics and Rail Agglomeration Area and Moment Arm

Please READ MORE for the video (full secreen is my recommendation) and document. If there was not mass of railway vehicle and gravity, vehicle wheels stand just on rail head level. In fact due to physics, wheel embeds to rail and rail embed to superstructure and superstructur embed to substructure and earth (action-reaction) So, vertical and horizontal forces occur elastical deformation on wheel, rail and structure. As well as static wheel and dinamic...
