  1. Looking at this last batch of photos it's interesting to see some details of the layout super structure. I would like to see more details of this aspect, which is often over looked.

    Things like the lighting rigging and frames, the trestles and the skirting/curtains - their design and how are they fixed to the layout.

    What is best practice?

    Can anyone refer me/us to further information on this aspect?

    Dropped you a PM!

  2. Emigration isn't really an excuse anymore, had another fight with the RCH tank chassis that put me off 2mm last time, just long enough to get comfortable with the RSU.

    Which was sharply followed up by a CCT chassis to fit under a PD Marsh body from the Sykes boxes at Tutbury.

    Which was going swimmingly until I realised I had only got wagon wheels in stock...

  3.  

    Where are the horns mounted? Are they behind the little grill on the grey bit below the coupler hatch?

    Yup they are - evidently the heater units aren't working, which isn't a surprise since they never got tested in my time. The temp sensor is on the front bulkhead nearly 2m inside the clamshell (which staff were cautioned against working in since there's no obstacle detextion)

  4. It is in order to bring a pan down before it tears down chunks of infrastructure. I can't remember the tolerance but it gets surprisingly high before it drops.

     

    The 800 pan still has a positive air feed

    through both carbons and an indication I the cab. I can't recall how it opened the vacuum circuit breaker though. Thankfully I'm 8 months clear of the shambles!

  5. Was it ever confirmed that there actually was an OLE defect ? The ADD I am familiar with consists of an air supply passed under the pantograph carbons, arranged so that if the carbons are dislodged or damaged, whether due to an OLE fault or a pan defect, the pan will lower. The procedure should then be to stop and examine the pan for any damage. Surely there would be an indication on the 800s of which pan had the ADD activation, or did both ? Regardless, an ADD activation should not have affected the ability to run in diesel mode, although if the pan was damaged and had become foul to gauge or the OLE the train would be stuck.

    The add also has an over height dump valve on the 800 leading to a choked exhaust that lets the pan sharply drop away from the wire then damps the travel to rest.
