As the country’s roads are at a standstill as panic buying continues to clog up petrol stations, That Engineering Chat changes track and looks at the complexities of designing for railways. Relec Electronics specialises in power supplies and displays that can meet the demanding environments of trains around the world. Nicole and Caroline talk to sales director, John Stone, about the temperature extremes, the power surges and different settings for supplies and displays that passengers take for granting – especially this week, as they take to the rails to avoid petrol shortages.
