UGL enhanced their standard locomotive by offering a Removable Second Driver Station (RSDS) in the driver cabin.
The existing locomotive was either fitted with a fixed second driver station or with a dummy structure with no functionality, that is an obstruction in the cabin. The RSDS provided operators of the standard locomotive the ability to reconfigure the locomotive from mainline operation to intermodal operation and back by installing or removing the RSDS.
UGL engaged Nova Systems to provide the design of the RSDS, the installation methodology and all associated systems engineering tasks, such as integration, requirements management and logistics.
Nova assessed the operation requirements from UGL, the operators and the drivers, some of which had conflicts to be addressed, such as weight and the ability to install/remove through the cabin door.
Nova worked with UGL to modulise the existing design by working through the design lifecycle and presenting a number of design reviews to show how the requirements are all satisfied and how the modulised design has the ability to be easily installed and removed.

In the removed state, the key requirements of sealed blanking plates and no holes on the floor were met to allow cleaning and maintenance by operators. The Nova modular design allows the RSDS to be operated in the same manner as the fixed second driver station, thus removing the need for training and additional familiarisation by drivers and the operators.
During the customer acceptance phase UGL senior management commented that they didn’t know which second driver station was fixed and which was removable, which was deemed a huge success for all parties.
