143606 passes Network Rail's buddleia nature reserve at Honeybourne on 29 July 2017, as it works the 5D94 08:30 Cardiff Canton to Long Marston ECS. I wasn't entirely surprised to be on my own here, as despite the novelty of an Arriva Class 143 on the Cotswold Line (a first in fact), most photographers still ignore DMUs. This is the first run of a modification contract, and so was definitely worth recording, despite the grim weather. Despite keeping an eye on its early running, I had only just arrived here, after deciding to leave home when it passed Cheltenham 68 minutes early. It was now running a staggering 102 minutes early!
