Christo, thanks for the construction plates photos, and the presentation

Here are some photos of the remainings of the "French Company" C.F.M.L. (Compagnie Francaise des Mines du Laurium) at Lavrio and Kamariza.
Elevator for the minecarts at Kamariza
One of the minecarts. Note that it is designed for dumping to the front.
The funnels through which the dumped by the minecarts materials pass, to fall inside the meter gauge open wagons (gondolas) which passed below the "bridge".
The water tank of the meter gauge shunting yard (διαλογή).
Junction of the former line. Only some ballast still exists...

The Γαλλική Σκάλα (=French Ladder) at Lavrio, for the loading of ships with the mine carts, and later with a conveyor belt.
The first railway tunnel in Greece, on the line of the Greek Company, at Kamariza
