technically as far as I can tell this train station is a station in name only, no passenger service comes out of this station, its currently used for the Revolution Rail bike trail. If this is the case, tags on the station building itself and the stop location could be updated to reflect its current non-rail station use perhaps with life cycle tags.

the canal section in this area should probably be tagged as derelict since its not in use and has no water here

canal in this section still has water in it, suggest adding water to the sections of the canal that are still open and have water in them in this area

user Milo Miller has put what looks like a lot of spam on the map, in particular in this area. I have tried to cleaned up what I can verify but others please take a look at the users changesets most are suspect and there is more to address...

changeset changeset/156505729 seems to have marked this bridge as access=private should it instead be marked as access=permissive since there are no barriers or signs at the start of the bridge from what I can tell that indicates public travel is prohibited, seems that only happens at the gate house past the turning circle. Verification may be needed here.

is this bus station better classified as a bus stop instead? node/2114017599

I dont think a park poi should be used to mark a park main entrance: node/11081394554 , and there already seems to be a poi for the gate here nearby, so suggest removing this park poi or changing it to some other poi type, the 'entrance' tag schema also doesnt apply here...

Escondido Village area can be considered part of Stanford U campus so suggest adding this to existing Stanford U campus relation or extending campus boundary to include this area

unclear if this airport poi node/1042092123 is still located here, at least where this poi is via latest imagery this is a stand of trees now, verification need
