Technology Doesn’t Have To Be Complex

This article on the Rail Tecjnology Magazine web site is entitled Easing The Capital’s Cramped Carriages.

On the London Overground, the Class 378 trains are Electrostars with an air suspension.

Note the rubber suspension bag between the bogie and the car on this Class 378 train. As more people, dogs, buggies and heavy bags are loaded into the train, more air is pumped into the suspension bag to keep the train level, so that the train rides better and passengers don’t have to step up and down to get in.

The pressure in the bag gives a very good estimate of the number of passengers in each particular carriage in the train.

The Rail Technology Magazine article describes how this information is collected and  then processed and distributed to the iPads and iPhones of station staff, so they can direct passengers to the least crowded parts of the train.

I have read that other train manufacturers are working on sophisticated head-counting software using CCTV cameras, as I saw deployed on a 141 bus in Transport for London’s Latest Plot To Get Us To Climb Stairs. That device has disappeared, so I suspect there were problems, privacy issues or it just cost too much.

The system on a Class 378 train must be a lot simpler and cheaper to install, especially if the train has been wi-fi enabled. The Class 378 trains don’t have wi-fi, but many Electrostars do.

As information is always key in any system, it can lead to various developments.

  • Modern station displays can be updated to show the train loading.
  • There may be cases where train loading affects the platform a train would use at a terminus.
  • Automated messages about train loading could be displayed on the train.
  • Detailed train loading information must be useful in designing a train interior and also station layouts.

I suspect that those behind this project have got lots of applications.
