Here is an interesting tidbit of info...which is a description of activity along the Somali Coast. It gives some more detail on the size of forces around the time of the Abyssinian Crisis 1935-36.
It indicates 10,000 men...a number I'd like to double check somewhere else if I could...it seems quite high....can anyone confirm? Still, in early 1938 the French put in 15,000 troops because of Italian activity so it seems reasonable enough that the Italian invasion in 1935 might elicit a similar response.

An accord is sign between the Italian Government and La Compagnie du Chemin de Fer Franco-Éthiopien. Italy’s conquest of Ethiopia and subsequent development program pushes the railway’s capacity to its limits. The railway modernizes its rolling stock with the purchase of four Fiat railcars and new locomotives. Night trains are scheduled.
The trip from Djibouti to Addis Ababa which once took 3 days and 2 nights with stopovers at Dire Dawa and Aouache is shortened to a day and a night. New panoramic passenger cars and a dining car are put in service to increase capacity and comfort. The line is double tracked from Ali Sabieh to Dire Dawa.
