the mentioned comments are spot on however the bushbury/low hill area is not the safest place to be hanging around. photo are only practical of trains from stafford. I would recommend penkridge.

Bushbury Junction is about 1 1/2 miles off the M54 Junction 2, head towards Wolverhampton, at second island turn left, go under railway bridge turn right at lights take first left into steel drive (factory on left). You will be right next to the line - good spot for photos (a box would help to see over fence when taking photos), parking on road (not a busy road it only leads to the bingo hall). No catering facilities on site. Chip shop, sandwich shop and a pub down the road by traffic lights.
