#110 — Why Digital Signalling Never Got Cheaper, with Andy Harrison

Twenty years ago the promise was simple. Digital train control would get cheaper, and ETCS and CBTC would become the default for every new scheme. Neither happened. Costs keep rising, and the system knowledge keeps migrating into the supply base.
My guest is Andy Harrison, a long-time friend and consultant to top railway clients across Great Britain, with four decades in the industry. We get into why the tipping point never came, what changes when the railway no longer holds competence in its own systems, why "change management" is far more than a new job description, and why zero disruption should be the default for bringing new signalling into service, not the exception.
