The traffic in coal from Dublin Port was from the CDL siding to Asahi, and I don't think Cawoods had any involvement.. The Cawoods flow as a short term flow by rail from Barrack Street to Arklow, with I believe Staffords of Arklow being the recipient.. The containers were shunted by road between warrenpoint(where the ship from Ellesmere port docked for the main NI flow) and Barrack Street.. The CDL yard itself could make a nice micro-layout, taking in part of Alexandra road and with the conveyor used to carry the coal accross alexandra road forming a nice scenic break.. Further down Alexandra road and the other side of that conveyor, the Boliden terminal could also make a nice micro-layout, with a prototypical wagon traverser being accessed by a sharp 90 degree turn off the main lines..
I would think there are plenty of other 90s/00s locations modellable including
-Kingscourt, with a small pad and covered shed used to store Gypsum which was loaded by a wheeled shovel into 4 wheel wagons(available from IRM), and also the possibilty of timber traffic, which was trialled in the 90s.. With a bit of alternate history, this could have become a regular flow.. 4 wheel and 62ft timber wagons aren't too hard to scratch build using Dapol and Hornby underframes, and plasticard to make the head boards and stanchions..
- Ardee Road, Dundalk, which replaced Barrack street which handled kegs and containers.. A relatively compact site, with a nice bridge to form a scenic break..
- NW wagon repair shop, with clever use of sightlines/forced perspective the Ballast bank could also be incorporated
- Cabra Cement depot(one I plan to do as time/kids/life permits), two/three sidings parallel to a twin track mainline, with bridges at either end for scenic breaks.. Cement trains arriving from the Heuston direction after a run around, and setting back into the yard.. The train would need to be split to be placed under the shed for unloading.. For added interest, a regular flow of passing trains made up of pretty much anything that ran on the Irish network transferring from Dublin port/Connolly to Heuston/Inchicore/Cork line.. Cabra also received a few deliveries of smokeless fuel(I believe in Fertiliser wagons) which could be easily modelled..
- Athy Cement Factory, a relatively compact siding alongside the Canal, with cement wagons being discharged into a silo for the factory
Castlemungret and Platin are probably a bit on the large side, but a taster of them could probably be modelled, with clever use of a backscene to give the impression of a wagon loader as part of a bigger plant
