Alstom Transportation Lead Engineer Interview Questions and Answers

Car window operates using DC motor. Position can be detected using limit switches or current sensing.

• Car window is connected to a DC motor which rotates in both directions to open and close the window

• Limit switches can be used to detect the position of the window by cutting off power to the motor when the window reaches the fully open or closed position

• Current sensing can also be used to detect the position of the wind...read more

BIM application in highway models involves creating a digital representation of the road and its infrastructure.

• BIM can be used to design and visualize highway projects

• It allows for collaboration between different stakeholders

• BIM can help with clash detection and reduce errors in construction

• It can also be used for maintenance and asset management

• Examples include the use of BIM in the construction of the M25 motorway i

I review/check work of an originator in Civil3D Models by following a systematic approach.

• I check for errors and inconsistencies in the model.

• I verify that the model adheres to the project standards and specifications.

• I ensure that the model is accurate and complete.

• I communicate with the originator to clarify any issues or concerns.

• I document any changes or revisions made to the model.

• I perform a final review before s

Roundabout parameters and values vary based on urban and rural settings.

• Urban roundabouts typically have smaller diameters and tighter curves than rural roundabouts.

• Rural roundabouts may have larger diameters and wider curves to accommodate larger vehicles.

• Speed limits, traffic volume, and pedestrian and cyclist activity also influence roundabout design.

• Roundabout parameters may include lane widths, splitter island wid...read more
