Default Streamlining...

A short video of three streamliners in operation this last weekend. All ran well although the T1 continues to dump all of its oil while it clears cylinders - I remember a discussion on this some while ago but can't find it and don't remember what the solution was.

One of the Coronation Scot coaches derails at 3:25 with a very nasty bang. Sounds much worse than it was.

Thanks for sharing, streamlined steam engines with their matching trains make a complete visual picture of the modern look the railways at the time wanted to promote whereas a streamlined loco on its own or on a generic train or freight makes them look a bit out of place in my opinion.
A good video of these great streamlined trains with magnificent matching coaching stock that we don't often see. Full marks for collecting the rolling stock and full credit to their makers!

How broad is that curve? looks pretty wide, what caused the derailment?

Nice collection of trains Robert and great video taking. It looks like they are RC and you were working that and the camera at the same time ???

Greg
Curves are minimum 10 ft radius - wider at the point of the derailment. The issue is the coach connectors which limit up and down movement between the coaches in the curves which makes them very susceptible to any ups and downs in the track. On a straight piece of track, the couplers are adjusted to give about 1/16 inch between the connectors which gives the streamlined look. But on the curves, they touch on the inside which limits movement.

No RC, but I will admit to an out of camera nudge when the T1 stalled on 'heartbreak hill'. The T1 needs some attention - steams very freely but seems to tighten over time and needs more throttle for the same speed. Could be as simple as the fact that it ejects all steam oil soon after start-up or could be the sub-standard o-rings used in the cylinders.

Yes Robert I have also noticed this problem (On the T1) with the front driver covered in oil (whitish deposit as it emulsifies) as oil leaks out from the gland boxes. In particular at slow speed: IE when starting a heavy train. The rocking of the engine is particular apparently to the duplex, as I have read many accounts of the real ones rocking (even the French PLM 2-10-2). So it is "prototypical". This stops as the engine gets under way and the steam and oil leaking from the gland box also. It seems like the O rings used in the gland boxes act like safety valves.When the engine is starting a heavy train, it lets out excess pressure... But it also lets out oil.
