In 1905, a tram service was also inaugurated, which linked the Three Cities (Birgu, Senglea and Bormla), Birkirkara and Zebbug. With two floors, 20 passengers could be seated and the rest, the majority of which were farmers carrying fresh fruit and live chickens, would be standing. The upper floor could accommodate up to 18 seated passengers, however no standing passengers were allowed due to the overhead electric wires.
