Here's another interior photo of GO Transit coach 2423 at Cochrane Shops from December 4th. This particular photo shows the car's layout between the ground level and the upper level. There are two mid-sections directly over the car's trucks where approximately 10 or 12 people can sit. This is also where the washroom is located. I'm standing in one of these sections looking towards the steps to the upper level along with the steps to the lower level and the car's doors.
