Perhaps they decided that running it on 2 trains was unsafe for their bank account?

It has been on one train all season, to the best of my knowledge, which isn't great considering it is one of the parks major attractions. Does anyone know what has happened to the second train?

It ran on two when I visited at the end of June. Only time this season I've seen it that way, but it definitely did. So the second train definitely can/could run, maybe my visit was a test? Might have something to do with the fact that it was a quiet day; on a busy day, dispatch times are so slow that people would be stuck on the brake run for ages. Not that that's any excuse.

Yesterday I had the worst ride I've ever had on Colossus, I had a gigantic headache and had to sit down and rest for a bit. Probably gonna avoid it next time, I think the ride needs ether new trains (Altair style), retrack or just scrap it. Don't know why the GP flock to this ride.

Also I heard the new soundtrack by IMAscore, not really a fan, its basically a remix of the island theme. Much preferred the old one.

Pullinger Signs (a sign and graphics company who have worked with Merlin on a number of things) last week posted this photo on Instagram of the fresh lettering they applied to the front of Colossus' trains, with it apparently not having been replaced since the ride opened.

It's only small but it's nice to see some work on Colossus taking place. I wonder what else they're planning?

It would make the area look a lot nicer. It is probably one of Thorpe most run down looking attractions. 

When I rode Colossus, I specifically queued 40mins for the front because of what I had heard about it’s roughness. The throughputs were quite poor as it was only running one train. When speaking to a host in the station he said that ideally they want to run two trains however maintenance have been doing work on the second train in preparation for Fright Nights operations. They seemed to be having a loading issue when I rode because with every load they had to release all harnesses and have them rechecked again, which slowed down times.

I enjoyed the rides layout up to the quadruple barrel roll where I thought it was pointless. I went on thinking I would feel sick after that part however I felt fine. The front row was pretty rough however a regular at the park I was sat next to did say how the front felt so smooth compared to the back. Next time I would be intrigued to see how rough the back is, even if it means I come off with a headache! I love the area soundtrack however I do think aesthetically it looks very tired. Thorpe Park needs a ‘Thorpe Loving Care’ programme to give Colossus a new repaint and all the walls and buildings painted up too.

I agree, Thorpe definitely needs some "Thorpe Loving Care" and Colossus is one of the major rides to start with.  It is a shame to see it looking a bit neglected like it did last year but hopefully something will be done.  

It certainly hasn't aged very well and is a far cry from when it first opened - it was lovely and smooth then

I also think the trains could do with sorting out as I always like to sit in the front of each carriage as there's more legroom, additionally, some less cumbersome restraints would be good too

I've only been to Thorpe Park the last two years, we've just booked our third stay for June. I can honestly say that it seems to be getting rougher each year. I do still love the ride but it definitely needs a refurb. Major track repaint is needed, when you look at the track now to when it first opened, the blue hardly shows anymore. The train definitely needs a redesign, the restraints are very solid and not cushioned at all and there's a serious lack of room. Our group that goes comprises of me (5'3 with a fairly slim build), my best friend (just under around 6ft, decent build) and then two other people who are either around 5'6 and on the bigger side, tall and on the slimmer side or around 5'4 and slim. I can honestly say that the amount of struggle that goes into getting into those seats is ridiculous, even for us smaller people. The amount of times I have hit my head on the restraints as I'm climbing in is too many to count. So definitely needs a more roomy design. And can I just point out: THIGHS! Does anyone else have the same issue as me and my friends where you end up with insanely trapped and pinched thighs by the end of the ride?

Were the restraints different? I'm not sure I knew that?

They were less bulky than they are now and much better in my view
