Germany between Hamburg and Cologne (green) &
BTE AutoReiseZug (also green)
Hamburg-Köln-Express (HKX) was founded as a joint venture in November 2009 between RDC (75%),
Locomore (17.5%) and railway investor
Michael Schabas (7.5%). Services were initially planned to start in August 2010 but this was postponed after the paths it had identified for its services were claimed by
Keolis for a proposed
Mulhouse to
Hamburg open-access service. Keolis later abandoned its plans and HKX was able to reapply for the paths. Operations commenced on July 23, 2012. In December 2015, RDC-owned HKX stopped operating the
Hamburg-Köln-Express, the operation was then carried out by the independent rail tourism company
BahnTouristikExpress (BTE). Following 2016 reports that the German motorail operator
DB Fernverkehr was about to terminate all motorail services in Germany by October 2016, RDC purchased a 50% share in BTE as the company had a number of car-carrier wagons in stock. Following the purchase, on 18 October 2016, RDC commenced operating
RDC Autozug Sylt car shuttle services from
Niebüll to
Westerland after securing a 10-year access agreement. Services were initially hauled by a
Transdev Class 251 while using BTE car-carrier wagons. BTE in December 2016 started operating the
BTE AutoReiseZug motorail service between
Hamburg and
Lörrach. Beginning in April 2017
Markus Hunkel took over management of Railroad Development Corporation Deutschland (RDCD). In October 2017, BTE and therefore RDC terminated the Hamburg-Köln-Express service without further notice. The service of the former Hamburg-Köln-Express was then restarted in March 2018 on the same route by the company
Flixmobility under the brand name
Flixtrain, but again with BTE as the train operator. The brand name HKX was replaced by the green Flixtrain label. In November 2017, RDC bought two
Siemens Vectron diesel locomotives for its
RDC Autozug Sylt car shuttle operations. In 2018 and 2019, BTE is also offering the seasonal
night train Alpen Express (winter) between the Netherlands and Austria in cooperation with the Dutch agency
Treinreiswinkel. In 2020, RDC started operating the seasonal night train
Alpen-Sylt Nachtexpress between the island of
Sylt and
Salzburg, Austria. In 2021, its operation will also include southwestern Germany with
Konstanz as destination by
dividing southbound trains in
Gemünden. In January 2021, RDC
Autozug Sylt was awarded the contract to operate the
Akkunetz Nord regional train network in the state of
Schleswig-Holstein, beginning in December 2023. The rolling stock,
battery-electric Stadler Flirt Akku trains, was to be provided by the tendering authority. The network was to comprise the following train services: • RE72 between
Flensburg and
Kiel, • RB73 between
Eckernförde and Kiel, • RE74 between
Husum and Kiel, • RB75 between
Rendsburg and Kiel, and • RB64 between Husum and
Bad St. Peter-Ording. In January 2022, the contract was terminated after legal action by incumbent
DB Regio. Instead of RDC,
Nordbahn was awarded the contract.
United Kingdom RDC was a shareholder in
Vivarail, a now-defunct company that converted
London Underground D78 Stock electric multiple units into
Class 230 diesel multiple units.
International night trains From December 2021, the overnight Amsterdam‒Zürich
Nightjet service has connected
Zürich via
Cologne to
Amsterdam. The train is operated jointly by
Austrian Federal Railways (),
Swiss Federal Railways (SBB) and
Nederlandse Spoorwegen (NS), using sleeper and couchette coaches leased from RDC Asset GmbH. The leased arrangement was planned to last until the construction and delivery of new fixed-formation ÖBB Nightjet carriages. In August 2021, Swedish rail company
SJ AB announced it had been selected by the
Swedish Transport Administration to operate a new
EuroNight service from
Stockholm via
Copenhagen to
Hamburg from mid-2022. The train is operated jointly with RDC and its subsidiary
BahnTouristikExpress (RDC), with RDC providing the rolling stock, and RDC/BTE providing crew within Germany. At their annual press conference in March 2025,
Swiss Federal Railways (SBB) announced plans to re-introduce overnight train service on the Basel to Copenhagen/Malmö route. The night train would be operated in partnership with Railroad Development Corporation starting from 2026, following the route of the previous
CityNightLine Aurora service that had not operated since 2014. Rolling stock would be cascaded from the Amsterdam‒Zürich service. ==Africa==
