I was wondering whether anyone can help me with the three OTP Machines that were at Bedford Engineers Sidings on the 4th and 5th of April 2016 ?
I managed to snap a pic of them with my phone from a passing train at 13:35 yesterday but can't make out the numbers on them. From my very limited knowledge (New to collecting OTP machines !), it looks like a tamper, a rail grinder, and something else, maybe a stoneblower.
They're all yellow livery and if anyone can help I'd really appreciate it.
