Looking aft in the Prinz Eugen's machinery control room on the Unteres Plattformdeck, compartment IV 7.3. To the extreme left one can see the ends of several pump and water diagrams for the electrical and boiler rooms. Slightly to the left of center is a message telegraph and repeater device. Underneath the telegraph box is a chart which describes all the pipes that run up the stack. On the right is an electrical telegraph and repeater with a 220 volt system layout diagram for the ship immediately underneath it. In the bottom right corner is a 24 volt generator.

Turning 90 degrees to the right from the prior photo, one is looking to port and sees the entrance to the compass / gyro room (compartment IV 7.2). The canister to the right, immediately in front of the access door into the fan room, is a fire extingisher. Photo taken in the Prinz Eugen's machinery control room, Unteres Plattformdeck, compartment IV 7.3.

Looking forward and to port in the Prinz Eugen's machinery control room, Unteres Plattformdeck, compartment IV 7.3, this view shows the compass room, the fan, and the exit hatchways. Above the fire extinguisher is a box containing electrical and piping diagrams for the ship. The crew would turn the handle on the lower right of the box to rotate through the collection of plans and bring up the diagram of interest. The list inclinometer and a chart for recording the amount of water and fuel onboard is immediately above the electrical / piping diagram box. Just to the left of the exit hatchway are diagrams for the fuel transfer piping lines in the bottom of the ship.

The hatch on the left leads to the Compass room (compartment IV 7.2); the small hatch in the middle behind the fire extinguisher leads to the air-conditioning room (compartment IV 7.6), and the hatch on the right accesses the stair's trunk.

Inside the Prinz Eugen's compass / gyro room, Unteres Plattformdeck, compartment IV 7.2, looking aft. The door to the machinery control room is on the far left.

Inside the Prinz Eugen's compass / gyro room (Unteres Plattformdeck, compartment IV 7.2) looking forward. The circular device at the bottom middle of the photo is the master gyro for the ship.

Taken from the floor looking up and toward the front of the Prinz Eugen's compass / gyro room. An open vent and the power cables for the compass are clearly shown.

A view inside the air conditioning / fan room (Unteres Plattformdeck deck, compartment IV 7.5) for the Prinz Eugen's machinery control room.

A cableway is shown inside the Prinz Eugen's air conditioning / fan room for the machinery control room.

Next to the Prinz Eugen's machinery control room is the stairway trunk access (Unteres Plattformdeck, compartment IV 7.5). This photo is looking at the forward, starboard corner of the stairwell access. The devices at the upper part of the photo are light fuses and circuits while the large gray box is a fuse panel. Just barely in view at the bottom center of the photo are the stairs down to the aft artillery plotting office.

Another view of the stairwell adjacent to the Prinz Eugen's machinery control room. We are looking to the aft, starboard corner of the room. The aft bulkhead is on the right, showing various bells, piping and other control indicators. The access hatch beyond the stairs on the far wall leads to the aft electrical regulator room. Up the stairs is the aft damage control center.

Looking to the forward starboard corner of the Prinz Eugen's machinery control room, Unteres Plattformdeck, compartment IV 7.3. The main panel in the middle shows pressure gauges, distance indicators, shaft coupling indicators, main engine RPM indicators, and the emergency engine order telegraph. To the right an overhead chalkboard was used to indicate the status of various items. The linoleum floor is showing its age.

This is the starboard-side view of the Prinz Eugen's machinery control room, showing the engineer's desk. The crew kept track of the open/closed status of all feed, steam, and other control valves throughout the ship on the multiple diagrams. At a quick glance they could quickly ascertain the current status in any compartment and quickly respond to an emergency.
