What did coordination of Somme logistics look like with the tech of the time?

I’ve been reading about the Battle of the Somme, and I keep hitting a wall trying to understand the sheer scale of the logistical operation behind it. Moving all those men, shells, and supplies for an offensive that lasted months seems almost incomprehensible from a planning perspective. I’m curious how they even coordinated something of that magnitude with the technology of 1916.

I've read that the Somme logistics leaned on long railway runs into a few front railheads, then hundreds of cart trains and horse teams ferrying shells and rations out to the lines. They kept temporary depots near Albert and Amiens, stacked crates, and tried to time trains to avoid collisions and gaps. It sounds almost mundane until you picture the mud soaking the wheels and the miles of trenches in between.

It still hits me how weather and mud could wipe out a day’s move. The field bakeries, ration columns, and ambulance cars had to survive the same weather as the men. Telegraphs and field telephones tried to keep the signals straight, but one bad day could throw a whole schedule off and leave units short.

Was the real bottleneck the timetables and signaling, or was it something else like the road conditions and the sheer pace of the offensive?

Sometimes I picture a dockside scene, crates rolling onto a quay and being loaded into trucks, and it makes the Somme feel less like a single battle and more like a stubborn, sprawling supply chain. The scale was different, but the idea of moving stuff day after day was painfully similar.
