Bike on train

So far as I know there is no problem with bikes on trains except between the hours of 8am-10am, and 4pm-7pm. I have taken a complete bike from Clapham Junction to Crystal Palace more than once, and it's fine provided I get to the station before 8.

I also notice that they allowed bike if you're going against the rush hour, says from Waterloo to Surbiton at 9am, instead of the other way round since there won't be many people heading to Surbiton for work from waterloo.
