Anyone tried this, or had any problems with them?

Says on their website that they wont carry them but i'm sure my trailer wont take up much more room than a large bag?

I've seen it done on the Glasgow-Oban train.

yep, done it a couple of times, glasgow – edinburgh and Glasgow – oban.

depends on what service you plan on taking. Edinburgh>Glasgow at rush hour is likely to be problematic…

generally speaking, scotrail staff are nice and sensible about bikes (it's the other passengers that were often pains in the ass when i was commuting with a bike). would hope they'd be the same about a trailer.

Thats what I thought, a bit of common sense and try not to make a nuiscance of myself.

Cheers
