I think you can bookmark services on all the sites mentioned here. Although, I suppose, some sites may delete the services once they've arrived.

I should have also mentioned Open Train Times. A bit more technical but the maps are useful for seeing where your train is, if it's delayed.
They look interesting. I'll try them out over the next few day.
GPSLogger seems to fit your requirements. It allows you to send location data to a wide variety of different servers, including URLs.
