The IFA tech trade show is not like CES in many ways, but transportation tops the list. Unlike the gadget gathering that’s owned my January schedule since 1998, Europe’s biggest electronics event takes place in a city with an immensely more advanced and useful transit network.
I thought I’d figured out Berlin’s expanse of U-Bahn, S-Bahn, tram, bus and regional rail lines fairly well, but this week here has taught me a couple of new tricks.
My first update came from taking advantage of Germany’s move to ease the pain of inflation, the €9 universal transit ticket it introduced in June. While I only had two days to capitalize on that promotion, buying one at a ticket-vending machine at Berlin Brandenburg Airport Tuesday still dramatically cut my trip costs over those last two days of August.
I enjoyed being reacquainted with the things I like about taking trains in Berlin. The rail system reaches almost everywhere (the now-shuttered Tegel Airport being a notable exception), trains come so often that waiting more than 10 minutes (as I had to do on the U5 Tuesday) comes as a shock instead of the usual, and the fare system prices every trip the same regardless of which exact service you take.
Thursday morning, I bought a 24-hour ticket at a ticket-vending machine. But then I screwed up by not getting a second one earlier than Friday evening, when crowds of IFA attendees lined up at the Messe Süd station’s TVMs. Only then did I think of downloading Deutsche Bahn’s app and using that to buy a ticket and avoid the unlikely embarrassment of having a fare inspector bust me for riding without paying.
Installing this app took only a minute or so, thanks to T-Mobile now offering full-speed roaming in the 11 countries in which its corporate parent Deutsche Telekom provides wireless service. Setting up an account and buying a 24-hour ticket took longer, thanks to the app demanding an account registration that included my street address and then not letting me select a credit card stored in Google Pay. But by the time I was three stops out of Messe Sud–the barrier-free, proof-of-payment regime let me board without paying upfront–I had my ticket.
And I’d learned that DB’s app cuts passengers a tiny break on fares, with a 24-hour ticket in Berlin’s A and B zones costing €8.80 instead of the TVM cost of €9.20. That makes DB Navigator a download I don’t mind having added to my small collection of transit payment apps—a set that now includes software for Austin and Las Vegas, but somehow not the city I’ve called home for more than three decades.
