Trains at Crewe (CLASS 325 SCRAP DRAG+ DRS FLASKS+ 47 and 56 LIGHT LOCO)

I went out to Crewe in the late afternoon and stayed around for about 4-5 hours. My main aim was to see the 325 scrap drag after seeing a path in as a 4Z headcode to Alexandra Docks. I ended up seeing a Colas Rail class 56, light loco WCR class 47, Flask train with 88+68 and some units on test which was all unexpected for me! unfortunately, these units are being sent off to scrap. I believe Royal Mail don't want any competitors to buy the unit so they are getting towed to scrap quickly!
