That surprises me, as Union subway station is well into the bedrock, which is shallower there than either Dundas at Queen. The subway tunnel as well along Front!The issue is Bedrock.
The reason the station is the way it is because of the need to tunnel around the bedrock.
Fun fact: Dundas is the shallowest station. It's platforms are closer to ground level than any other.
When the station was being constructed the soil conditions in the area prevented the station from being built any deeper.
It would have been almost impossible to build a connecting passage above the tracks.
I'm also surprised it's shallower at Dundas than Queen - as generally the overburden layer gets thicker as you go north.
Looking at the geologic data for the 15 Richmond East site, the bedrock is about 10 metres deep at Richmond and Yonge. Up at Gould and Yonge (335 Yonge Street) it is about 15 metres deep.
It would appear that the lack of mezzanine at Dundas was a choice, likely cost-saving. Value engineering strikes again!
It should be enough, but if one detail (the time or bus number) per haps is slightly wrong, then the wrong driver may be identified. Another piece of data doesn't hurt.If the complaint is legitimate, the bus number, location, and time should be more than sufficient enough. And if the complaint is not legitimate, force them to think a little bit at least, rather than handing them on a silver platter the identification to crucify the driver.
I figured out later, looking at the transit data, that I'd misidentified a driver I'd reported based on time and place, looking at the run data (for the record, it was a compliment, not a complaint).
