A ship load of new CSR built NHHH coal hoppers arrived in Newcastle last week.
NHHH rake 98011-98012 are the original pair which have been in operation for quite a few months now (maybe years). The light blue is an easy identifier.
Newly delivery NHHH rake 21 (98211-98214). These are 4-packs, rather than the prototype 2-pack.
NHHH 98211 is the lead vehicle of rake 21.
