This is how we’re future-proofing our 481 series!
In September 2004, S-Bahn Berlin took delivery of its last series 481 quarter train. Back then, the new stock had radically rejuvenated the existing fleet, dropping the average age of active vehicles from 55 (!) to six years.
This is how we’re future-proofing our 481 series!
In 2019, we started future-proofing this series, the backbone of our Berlin S-Bahn fleet. As part of the Project Longevity renewal programme, all series 481 quarter trains are put through rigorous testing at the Schöneweide S-Bahn workshop and depot. By mid-October 2023, 300 retrofitted vehicles had already been sent back on the track.
Our people – our expertise!
We’re especially proud that all tasks are completed in-house by our own S-Bahn-technicians. Until 2024, approximately 360 trained professionals at our Schöneweide location will spend a good third of their working hours on nothing but Project Longevity. A total of 50,000 engineering hours will be required.
At the heart of these retrofitting measures: a thorough inspection of the railcar bodies with special focus on entry-area girders, corrosion damage, and driving switch or electrical switching device replacements. Since this requires prior removal of all interior fixtures and fittings, we decided to go all in and completely replace everything inside, from seating and partitions right down to the flooring.

What’s more, the overhauled carriages are also fitted with additional horizontal handrails and new, tactile door opening buttons.
Brand-new CCTV monitoring inside the train will enhance the sense of ride safety.
But it’s not just the inner values that count
The 481 series will also receive a sleek new look inspired by the new 483/484 series S-Bahn design, upping the ochre and dialling down the red. Visually impaired passengers will appreciate the black paint finish of the doors, while other passengers with physical disabilities benefit from special pictograms highlighting the position of wheelchair bays inside the multi-purpose carriages.
Investing in the future
The complete overhaul of 309 vehicles is made possible by a €155 million investment by the German federal states (as part of the Interim Agreement).

Make do and mend...
Finally, we take you on a little photo journey. Experience what an old S-Bahn of the 481 series has to go through in order to shine again in new splendour at the end.

Soon-to-be history

Out with those seats!
First, the old upholstery has to go, leaving nothing but the steel framework.

All wired up

In-depth insights

In case of emergency ...
The only thing to remain in place are the emergency door opening buttons. At least for now ...

Appearances can deceive
From the outside, it’s (almost) impossible to tell what’s going on inside.

Trial separation
During renovations and retrofitting, the car bodies and bogies are separated. (The car body in the background belongs to a 485 series.)

A bit of polish

Wave good-bye to the gloss
Take a good look: this old design featuring a red stripe will soon be history.

Project longevity
While the S-Bahn’s traditional colour scheme, based on red and ochre, remains the same, both hues are now a few shades lighter.

Black is beautiful
In line with the 484/485 series S-Bahn look, the improved and reworked 481 series now also sports black doors.
