I had a look at your photos, and clicked on your link to your own site. You have some very good photo there. I really liked the reflection shots in the tunnels, and the graffited (excuse spelling!) wall in Botanic Gardens station. I tried to look at your Greenock ones, but they are password protected. Any chance of the password? I used to work freightliners through the old Princes Pier line tunnels, back when I was a Secondman at Polmadie, until it closed in either 86 or 87, cant remember which. I was actually on the very last liner to come out of there when it closed, and to show how long ago we're talking, we had a class 26 that day which was pretty unusual, as we normally had a 37 & a 20 in multiple. I seem to remember there were 5 or 6 tunnels in all, starting from Container Base Junction on the Wemyss Bay line, till it came out at the base itself. It was not unusual to be heading down the branch and encounter many of the locals using the line as a short cut, walking their dogs, or just sitting on the tracks drinking some of the Monk's Finest. We usually got bottles or ballast lobbed at us around Whynhill. The normal formation for the train was 15 flats and 2 locos. Due to the constraints in the container base, we had to do a lot of our shunting within the last tunnel itself, which meant eyes streaming from the combined exhaust smoke from the locos! A lot of the Secondmen hated the job for that reason.
I also noticed you went out and took some shots at Dalmuir Riverside branch. When I was at Yoker that line was still in use by the whisky trains for Chivas Regal. It's because of that branch that the down line (westbound) is bi-directional between Clydebank station and Garscadden. It was quite funny running east bound out of Clydebank and running parrallel with a loco and a single tank wagon going the same way next to you. Back then, the Rothesay Dock line was also still open, and sometimes all movements within Yoker depot had to come to a stand to allow a pair of class 20s to trundle off the branch and through the depot with a fair train load of scrap metal. At first, they used to come out of Yoker and run to Hyndland West, then Anniesland, before turning onto the still open line through Kelvindale to Maryhill Park Junction. (This would have been 1987 0r 88). After this line was mothballed, the trains had to continue from Anniesland right back round to Dumbarton East, where they could enter the loop (it ran from Dumbarton East right to Dumbarton Central) so that the locos could run round, then head back to Knightswood North Junction then Maryhill Park. Some detour because of closing a branch!
Anyway, I hope I haven't bored you too much, it's just that seeing some of your photos brings back memories of things I'd forgotten all about.
