Re: Construction of a Test Track

Ni-Silver will expand about 15% more than Steel. For temperature difference of 10 DegC then for a 500mm long rail the gap should be 0.08mm for Ni-Silver and 0.07mm for steel based on the above criteria. It's a linear relationship so double the temperature range double the gap likewise the rail lengt...

Re: Model Facing Point Locks

FPLs normally have a cover to protect the FPL so you can't actually see it.

The nylon printed are 3x the price of the the acetal (?cast). Is nylon better?


Not really you get two pairs of nylon for £12 and the acetal is £2.88 for one, which is £11 odd for the two pairs.

Re: Yard Crane colour

In general the Midland painted metal bits Venetian Red (an iron oxide based paint - as per the above photo - as it was cheap and hard wearing) and wooden parts tended to be a light cream colour such as Denby Cream.

Re: Construction of a Test Track

The estimated gap between these two lockbars is about twenty feet more than, say, an M7 hauling a 3-set of LSW 56-footers. That would mean that, as the last bogie clears 13 Lockbar, 14 Lockbar would be free for no more than the time it takes for the M7 to cover that twenty foot interval. Acceptable...

Thanks for the clarification of the operation conditional yellow signal. Would that signal then allow a train to depart from the headhsunt onto the running line up to signal 3? I shall amend the plan and see if I have got it right.

When OFF yes.

Yes the original axles are 2.36mm and fit smoothly through the bearing which I've tried to measure and believe it to be 2.40mm, the Gibson axles measure 2.46mm.

The Mazak will continue to self destruct and in doing so will expand. Your repair will be short lived and has the potential to damage your body moulding into the bargain (if it hasn't done so already).
