Traction & Power
BACKGROUND
• This is a new stream in the new Higher
Diploma in Electrical Engineering;
• This stream aims to fulfil the REW Grade B
academic requirement; and
• This stream covers the works in traction and
railway system, locomotive and electrified
trains, rolling stock and depot, and vertical
transportation system.

Traction & Power
Potential Empolyers
After meeting with KCRC, MTRC and L&E
Co., they are in general supporting this
stream, especially the term time project and
placement.
Potential employers not only include MTRC
and KCRC, but also their consultants and
contractors.

Objectives of the Stream
Traction & Power
• Aim at teaching students the theories of
advanced electric drives used in HK,
• Knowledge of power system specified
to MTR (1500Vdc) and KCR (25kVac),
and to their stations (ELV in BS area);
• Concept of Rolling Stock Maintenance
and signaling/protection in local
traction system.
