Yes ... sort of. That ramp leads down to a currently unused platform between tracks 9 and 10.
The tracks are numbered, not the platforms. Note the location of the sign, centered on the track where it could indicate a train served from either side. The high level platforms are between tracks 8 and 9, tracks 10 and 11, and tracks 12 and 13. Track 14 is a storage track not accessible to passengers (no platform) and tracks 1 through 7 are Metra tracks in the lower level north of Randolph St.
The old low level platform has been maintained between tracks 9 and 10. This platform was used for the diesel set borrowed from Metra from 1989 through 1993. The tie down remains in service (powered up) at the end of track 9. If NICTD starts a West Lake service with low platform equipment it will be able to use Track 9 or 10 and the low level platform at Millennium Station.
But there are support pillars on that lower level platform, so if the wizards want to push their carts into the right one to get to platform 9 3/4 I suppose they can try. (NICTD's high level platforms at Millennium Station do not have pillars on them.)
