 The lifeboat crew of the

 36.5-meter lifeboat with a
 top speed of 25 knots: the
 Harro Koebke. It started
 service a few weeks ago
 at its base on the island of
 Rügen. Now the lifeboat-
 men are making their oc-
 casional home comfortable
 and getting the boat ready

Rail                     MTU conquers the Romanian rail market one train at a time


                          With 20,730 kilometers of track, the Romanian railway
                          system is one of the longest in Europe. But the 1,200 loco-
                          motives and 300 railbuses often trundle along the deteri-
                          orating tracks at little more than walking pace. With the
                          help of modern diesel engine technology from MTU
                          things are set to get better on the Romanian railways.
                          Railcars are to be fitted with modern Powerpacks from
                          Friedrichshafen and old locomotives repowered with Se-

They will make the railcars fit for purpose on Romania’s updated local rail transport services.

The fitters at the Romanian railway engineering company Remarul treat the diesel engines supplied by MTU as if they were as fragile as an egg. They are to be used for
modernizing railcars and so will make a decisive contribution to updating the dilapidated Romanian railway system.

  Railway	modernization	in	Romania

  Romania is investing 17 billion euro, partly financed by the EU, in modernizing its railways. MTU is
  supplying the manufacturer Remarul 16 Februarie S.A. with Type 16V4000 R41 diesel engines for
  repowering locomotives and Type 6H1800 R84P Powerpacks for new and refitted railcars. The Roma-
  nian rail network extends to over 20,730 kilometers of track. Operating on it is a fleet of roughly
  1,200 locomotives and around 300 railcars.

                                                                                                                  There are old and new locomotives to be seen on the grounds of the Remarul rolling stock plant. They are being modernized as part of the process of modernizing the
