Railway Conversations with Doc Frank

CBTC has been the world's de facto metro signalling standard for 40 years. In all that time it has never been made interoperable across suppliers, so why is the question suddenly back on the table, and why is it proving so hard to answer?
My guest is Dr Alan Rumsey, one of the genuine authorities in this field. Alan chaired the IEEE working group that wrote the original CBTC standard, and he has spent a 45-year career on advanced train control projects across North America, Europe and Asia.
We start by getting our terms straight, because in this industry the same word too often means different things to different people. From there we work through the real questions. Why would a railway want interoperable CBTC at all? What does interoperability actually mean once you get specific about it? And if the business case stacks up, how could the industry ever get there? Along the way we look at why New York took 25 years and a fortune to achieve it, why ETCS managed what CBTC has not, and what China's interoperable standard might mean for the established suppliers.

Thirty-five years ago, a small international team sat down to write the first specification for what would become the European Train Control System. Bogdan Godziejewski was one of them. So when he says ETCS rollout has been disappointingly slow, it carries the weight of someone who has followed the system from its very first idea to today.
Bogdan is the immediate past president of the Institution of Railway Signal Engineering (IRSE), Rail Director and Fellow at Mott MacDonald, with more than 40 years of international experience across the Netherlands, Belgium, Australia, Denmark, the USA and beyond. Between 1992 and 1996 he worked at the European Rail Research Institute on the first ETCS system requirements specification. Few people are better placed to take stock of where ETCS now stands.
In this conversation we cover why deployment has crawled in the big countries while smaller ones forged ahead, what Belgium did differently to fit its entire network in record time, and why a countrywide vision matters more than the technology itself. We get into repeatability, approvals and testing as the real levers of an industrialised rollout. We also turn to Bogdan's IRSE presidency and his Generation Unlimited theme: bringing younger people into the discipline and building bridges between generations.

Chris Gibb spent 45 years in high-profile positions across the British railways. He knows what a successful railway operation looks like — and right now he is publicly challenging the plans for High Speed 2 (HS2). 
The issue is not the construction. It does not even impact the High Speed Rail service between London and Birmingham, what most people think HS2 is about. It is the impact of the new HS2 train fleet that continues around Birmingham on the West Coast Main Line to the North. Chris foresees a substantial reduction in capacity from today's fleet travelling up North, at times when more, not less, capacity will be needed. And he tries to do something about it before procurement decisions cement a future capacity shortfall. It is a lesson about long-term planning decisions and their consequences.

GSM-R is on its way out. FRMCS — the 5G-based successor for railway radio communications — is on its way in. But the migration from one to the other is anything but straightforward.

In this episode, Doc Frank talks to Rob van Looveren from the Netherlands, a railway consultant with hands-on experience in FRMCS specification work for freight trains through the European-funded FENIX project. Together they unpack what the migration from GSM-R to FRMCS actually involves: the technical challenges, the planning complexity, the freight operator funding dilemma, and why a bistandard onboard approach is likely the only migration strategy that really works.

The Netherlands context provides a useful European lens — and the comparison with Australia's situation turns out to be more interesting than you might expect.
