Does LTN work well over longer distances, or is it better to build local warehouses?

Hi All
Im just going through retro fitting LTN into my existing modular base. Im now wondering how I should set up the ORE deliveries.
In Vanilla:
All my smelting is done in pods. each pod can smelt everything with one delivery station and 1 supply station (2-6 for ore, 2-4 for smelted goods - see here: https://www.reddit.com/r/factorio/comme ... t_smelter/ ). The way it worked was that each delivery had the same name and would be deactivated when the ore buffer level went above the HIGH threshold or a train was curently unloading, and re-activated when it went below the LOW threshold. (about 80k HIGH and 10k LOW ore/stone). Because there are several smelters, the trains would go and fetch a load of ore from a mine 12k at a time. Then on the way back, if it was currently routed to one that de-activates, it could just get re-routed to another active station. If all smelters became de-activeated, the ore trains would go into an ORE stacker, so that when a station needs more ore, they could simply stampeed to the nearest station in need of supply. This way, no warehousing is needed and there is a good throuput of trains to provide ore. Because of this, I didnt have much stacking at the stations.
Simply retrofitting gives me a dilemma. I cannot allow too many trains to travel to the station so the line doesnt get blocked, but the longer travel times means it could deplete the buffer while the train is in transit. If I increase the number of trains allowed at delivery, I increase the chance of backing up the trains onto the mainline.
Is this a LTN limitation? is there anyway I can "warehouse" the trains like I do in vanilla? or will I simply need to create an ORE warehouse where ore is dumped then another LTN network supplying the ore on the last mile on the main LTN network?
Any help or ideas appreciated.
