I will follow this thread with interest because I grew up in Ealing in the 60s and remember the 'Golden Mile' on the Great West Road very well. At Christmas the factories and offices were always illuminated and Dad would take us for a drive there to see the lights. Brentford station at the Half-Acre would be where we went on holiday from - up to Waterloo or Clapham then down to the coast! As a small child I watched the end of steam on the western region from the UD milk depot depot near West Ealing station or on 'Jacobs Ladder' footbridge which crosses the multitude of lines there. Then later when I was mobile I would cycle to Southall sheds and like a previous poster, stand on the footbridge there or sneak down into the sheds for a nose round. As for what ran on the Brentford branch I can confirm there was a Pannier tank in the early/mid 60s. I used to play football in Elthorne Park and the playing fields overlooked the Grand Union Canal, bluebell woods, the pig farm, and the old branch line beyond. I would often see the old pannier chugging up and down the line. Once for fun we hid along the track and bunked onto the back of the waggons jumping out again near Brentford. We then bunked into a truck at Brentford to get back up to Hanwell! Happy days...
