Interested to know what powers this. OpenTripPlanner[1] certainly provides all the features required but needs a revamped front-end. Like this, basically.
I believe they power themselves using open sourced data like that from Transport For London. I think they also plug into some other apis for things like cycling routes.
That would be a wasted effort then, given that OpenTripPlanner does the same. But maybe there are performance restrictions or similar.
