It's somewhere between Wombwell and Stairfoot, i have been past it on my bike whilst on the Trans Pennine Trail.
it used to be at broomhill just off the roundabout (the roundabout between bramptons 'brewsters' and darfields cathill roundabout) but it isnt thre anymore it kept getting vandalised so they removed it and have since built houses.</p>
RE: it used to be at broomhill that used to be there when I lived at Broomhill!! Yes there's houses on that site now. When Thomas the Tank was there, some saddo's complained about the company, cos they said it's breaking copyright laws with the thomas the tank character!!
