How does the Luas get electricity?

How does the Luas get electricity? The power supply for Luas is delivered from electrical sub-stations at 750 volts DC via an Overhead Catenary System (OCS). The OCS is supported by poles or anchored to buildings adjacent to the railway. The 750 volt DC supplied to the trams is converted to AC current to power three motorised bogies on each tram.

Are trams obsolete?

Are trams more sustainable than buses?

80% x 90% gives a drive efficiency of 72% for an electric bus. A tram is effectively plugged into the mains and avoids these storage losses. Trams weigh significantly more than buses. Per passenger, they need more energy to get moving from a standstill.

Are electric trams sustainable?

Low Carbon Emissions: Trams have minimal carbon emissions making them an ideal option for eco-conscious individuals. Not only do they produce less pollution but they also emit less greenhouse gases into the atmosphere. Efficient use of Energy: Trams run on electricity which makes them highly energy efficient.
