G-Line on GWR Uk Train

I’ve been considering buying a G-Line for a while and went to test ride one in London last weekend, I was very surprised on the width and was concerned how they would deal with being stored a train. This morning I finally saw one for the first time on a train I’d actually be using and I do feel this is very awkward and takes up a lot of space.

Do any of you travel with a G-Line? What are your thoughts? Note: On the bottom rack there was a normal Brompton 16 as a size comparison! Figured this may be useful for other people too 👍
