Giant Escape 3 Hybrid size small

What happened

I locked the bike at the Clyborn Metra stop and got on the 7:40am train toward Kenosha. I didn't get back until maybe 6/7pm, and when I returned, it was gone. I locked the bike with an ABUS U lock and locked the frame to the bike rack. When I returned, there was not sign of the bike or the lock, and no shavings on the ground that I could see.
