Great blog - no economic details though? How much is it costing? how is access to the fibre working?

What about fibre/equipment outages and getting access track side?

For indoor coverage like this we believe that Wi-FI is the right answer also but we also believe that there are interesting applications that the mobile network can deliver including getting the signal to the train and leveraging NB-IOT so for us working on a converged solution is paramount.
