Yes
1. Stetchford has 3 platforms
2. There is a extremely infrequent service between Birmingham int. and Walshall. I have only seen it once.
3. The West Coast Mainline and the Stetchford-Aston line.
Originally I was down to deciding between Stourbridge Jct and Stetchford, and I chose Stetchford because I knew more about it. Bad luck on the first guess!
