this is missing my original talk.
IN the chicago area we have 3 railway company’s operating the system, and one had signs left up from the old days
which in watching the train come into that stations platform  did not stop at the sign based on the number of cars + the
diesel engines or engines. which could be 5, 6, 7, or 8 cars, we stop at 8 here. 1 or 2 engines.
i should say more here, 1.who is driving the train, 2.what co. does he work for, 3.how long is the train, 
4.how long is the platform, 5 what is the time of day, am rush, pm rush, midday,  evening .  6.   out of all the cars what are 
being used, open, 7. weekend, or week day, 8.raining or snowing, 9.end of the line, 10.is the platform so short
that only 2 cars will fit. 11.is the train pushing or pulling. (it does not work here you can not tag all 400 platforms the same.)

>>>If you find something wrong - correct it.
>>>If the things mapped are deceitful, malicious etc then report it to the DWG to prevent more of the same.  
>>>If the things mapped are better than what was there before then I would call them improvements and thus beneficial, no point in being upset by it.
>>>Being local is not a requirement to map, get over it. Local knowledge is beneficial as it aids mapping things that have local characteristics - like where trains stop
