I see that the Eglinton-Crosstown LRT could have 6 major stops/stations.
The airport terminal will be a major terminal requiring 24 hour-7 day access. This station will need to accessible to everyone with luggage. That means no stairs, but ramp access to the airport terminal. Informational messages would have to be in several languages (not just English and French) and stick-figure signs.
The Jane stop will be a transfer point with the Jane LRT. There should also be a short-turn crossover to handle long trains to return east.
The Allen Road station will be a transfer point with the Spadina HRT. There should be crossovers at both ends of the station, in case of problems with the line. It will have to handle large crowds of commuters.
The Yonge station will be a transfer point with the Yonge HRT. As with the Allen Road station, there should be crossovers at both ends of the station, in case of problems with the line. It will have to handle large crowds of commuters, as well.
The Don Mills stop will be a transfer point with the Don Mills LRT. As with the Jane stop, it should have a short-turn crossover to handle long trains to go west. Because of the proximity of the Ontario Science Centre, it will be also be a major destination (if the Science Centre could decrease the distance to its entrance to avoid its parking lot).
Last, and not least, is the Kennedy station. It will be a major transfer point with the Bloor-Danforth HRT, the Scarborough-Malvern LRT, and the Scarborough RT (unless it becomes an extension to the Eglinton LRT). Large crowds of commuters will be expected to be handled.
All six of those stops/stations will need to be major focal points for the line. All will need to have crossovers, and can expect large crowds.
