Strange wagons and loco

[GNRi1959]

Pictured during track relaying at Omagh - anyone know the wagon type in shot and also is the loco an LQG 0-6-0 though it appears to be marked D No.119

Can anyone shed light on it please?

Yes it’s an LQG. Originally 78 ‘Pettigo’ built 1908, re numbered 1937, withdrawn in 1959. The D refers to the power class, not the loco class. The power class rating allowed planners to allocate locos for particular tasks, D being heavy goods. Most famous D class on GN was the SG3. First wagon looks a standard GN open. Others are ballast I think.
