David Martin, Chief Executive, Arriva

Why is he on the list?

Perhaps the key influence on forthcoming consolidation of European passenger transport.

What kind of year has he had?

Deutsche Bahn has made good on its promise to respect Arriva’s skills and independence and now refers to Arriva as its “entrepreneurial arm”. It puts Martin, a veteran of around 200 M&A deals, in a position to do what he enjoys best, leading business development. Financial statements suggest solid if unspectacular growth in 2011.

What’s coming up in 2012?

DB’s strength alongside Martin’s proven business building record appears a uniquely powerful combination. Expect Arriva to expand market share through the cannily priced bids and acquisitions that have, with the notable exception of UK rail, characterised Martin’s career.
