Can I ask where you've got 18 months from? Are you merely supposing 'what if the line was closed for 18 months?' or something more substantial?
(Googles Dingwall temporary Light maintenance depot...)
It was purely a hypothetical- I was guessing that such a timescale might make arrangements for servicing units trapped, or make it worthwhile swapping them by road- as I understand it roads in the area aren't the best for shifting units on low-loaders, something along those lines was mentioned during the Pont Briwet closure.
I may be misremembering exactly what the arrangements were with Dingwall, though that too was quite a long closure while the bridge was replaced. I know that services North of Inverness were operated though, and with LHCS too.
