En route to the front line
Four carriages loaded with goods and soldiers are travelling round curving rail tracks. The soldiers are precariously balanced on top of the goods. There is snow on the ground and they are all wearing heavy coats.
Secure communication and supply lines are all vital to an army's success and new, makeshift roads and light railways were being erected constantly, to keep supplies and men moving to and from the front line.
