I went to the 7mm NGA open day with Allt-Na-Ballt yesterday. Across the aisle from my layout was Chris Ward's 3D printing trade stand... Needless to say temptation got the better of me and I bought an O scale tank engine from the discount box (always the skinflint). These photos were taken while work was in progress on the loco. It will eventually be in the standard LE&FLR livery - rust.
First impressions yesterday was that it was too large for the LE&FLR, that's why it was after lunch before I finally decided to buy it, and it is indeed just to big for Allt-Na-Ballt. Having tempoariliy fitted a mechanism, hence the Blutack, it turns out that the cab roof fouls the tunnel but the loco will run OK on Lochside so it has a little back story. It's too heavy for the bridges on the line between Lochside and the junction so it is confined to the section between the pier and the cannery, much as the aluminium factory in Fort William used a steamer between the pier and the factory but only lightweight diesels and speeders on the line from there to the dam at Loch Treig.
She is unarguably a big one, probably the maximum possible on 18 inch gauge... I mean the loco, not the young lady on the footplate! This is because the model was designed for 1:43 so I will add a false floor in the cab to make it better suit the 1:48 or 1:50 scale figures used on Lochside.
The unfenced nature of the line means that a steam loco needs skirts fitting to protect other road users in the area around the pier. This will hide the Kato mechanism nicely when done.
