|Sentinel 9622 at Teifi Valley Railway 18th September 2011|
A lot can be learned from examining other similar locos. 9622 is substantially different from 7109 as it benefits from 31 years of development. More perhaps in another article; however, one of the main reasons for the visit was to find out about the construction of an ashpan. Whilst drawings depict what is to be made, sight of the real thing really helps in understanding what's required.
Having said that, whilst 9622's ashpan matches the drawings, 7109's will have to be different as there are only four mounting points as opposed to the five shown here.
