How do you stop sand drifting onto railway lines in the desert? How do you ensure that trains moving at 250km/h through remote areas remain connected to the internet? How do you prevent humidity from damaging your state of the art communications systems? And how do you stop fine sand particles drifting into your train ventillation system and causing problems for passengers?

I was lucky enough to get some of the answers from prominent organisations such as Alstom, Huawei Enterprise, Dar Al Handasah, URS Scott Wilson and Arup. The feature will be published tomorrow in the MEED Rail Report. Here is a taster below:
