The monthly Anglia test train returning to Derby this morning. A merest hint of clag as 37425 'Concrete Bob' leads Colas Rail 1Q86 March Down R.S. to Derby RTC past Three Horse Shoes signalbox at Turves. 37402 on the rear. #ConcreteBob #Colas #Fenland 26/4/25

A Colas test train with Regional Railways livery 37 on the front and yellow coaching stock. The 37 had just opened up with a nice cloud of clag and given the folk on the footbridge some tones as she approached us

A fine sight at Foxcovert Road footbridge this lunchtime, #ConcreteBob 37425 leads the monthly Colas Rail Anglia test train back to Derby, this time running as 1Q86 from Welwyn Garden City FD due to engineering work between Peterborough & Ely. #Colas 29/3/25
