Probably another couple of months, the intention was for a present day version of course the Portmadog bypass and the revamping of Harbour Station is messing that up a bit, as they appear to sticking to the last published plan, I may just jump the gun and do the revised harbour station. I'm off up there in just over a week for a couple of days just to check a few things out. Using the new layout would make creating sessions a lot easier than all this shunting WHR stuff.
However, I'm backing up as is first. The DEM I knocked up covers the Brygwn Branch and quarries, currently, I've put the footpath on the lower bit for now so should be easy enough to "Restore" the branch, also got the lower portion of the Croesor Tramway from around the first incline to Croesor Junction plus redo Porthmadog in it's slate days and undo the new deviation bit's of the WHR and FR drain a large puddle and delete a few thousand trees!
