The earlist part of this branch was the 1.05m gauge Tramway
Libanais, started in 1895, which reached Maameltein in 1908.
In 1942 British forces had completed a standard gauge line to
Tripoli as part of the HBT (Haifa-Beirut-Tripoli) line.
After WWII under the NBT and later, the CEL, a passenger service was
set up between Beirut and Tripoli, with a weekly sleeping car that
connected to the Taurus Express at Aleppo.
