This machine has been at a site in the south of the UK undergoing a major overhaul and the conversion work for use with the basket, as we are the Mecalac dealer we have supplied quite a few parts for this machine.
In TXM and formerly Fastline ownership this was fitted with a conventional excavator bucket. Although pictured without a bucket fitted, the pictures of 6337 show what this machine would have looked like.
The gap in sightings is interesting. Whilst not recorded as such, sightings suggest that in 2011/2012 this machine spent a long period at Knottingly. Was it actually owned by GE Rail Services in this period?
As an aside, these Mecalecs are either loved or loathed. Whilst dated technology now and limited in terms of capability, on the right job with the right operator I understand that these machines outperform others particularly on drainage work. Hence why money keeps being spent on them.
They are both still there, so could have been either of them. They have been parked all week side by side, so looking from the A1 it has looked like only one was left on site. I passed by tonight and one of the grinders was in the shed and the other was in the yard. No sign of the ballast regulator though.
