Carlos Casanueva is an Assistant Professor in Rail Vehicle Technology at the Royal Institute of Technology (KTH) in Stockholm, and member of the ECO2 Centre for Vehicle Design. He obtained his PhD in Mechanical Engineering in 2010 at the University of Navarra studying the dynamic behaviour of variable gauge wheelsets for high speed trains, and studied the optimization of wheel profiles for freight vehicles during his postdoctoral period at KTH. His main research interests are wheel and rail damage, active suspension systems and improvement of freight operations focused on sustainability.

Some years ago, with a sudden and drastic reduction on the number of honeybees, scientists realized that if these insects disappeared it would be the end of agriculture as we understand it, as they are the main drivers of agricultural […]

Unlike road vehicles, all rail vehicles run through exactly the same piece of track and they cannot drift away to avoid a bad quality rail. Moreover, the contact patch between wheel and rail is a steel-to-steel contact with a small […]

 
Humans can build and use the most sophisticated tools. One of the reasons is the configuration of our hands, which enable us to hold items in a very convenient way. But further than that, we can actually grab items […]

High speed trains are the best example of vehicles that, although operating at somehow extreme conditions, are very comfortable. And by comfort I mean that the vibration level that passengers feel is relatively low. The components that allow this level […]

 
Easter Island is an amazingly mysterious destination due to the moais, megalithic statues resembling human figures that were built by the Rapa Nui people between the 12th and 17th centuries. These magnificent volcanic rock statues […]

Scientists have always peaked into nature in order to mimic its most interesting features into industrial processes. This adaptation process is called biomimicry, and the most recurring example is the history of how the Swiss engineer George de Mestral invented […]
