many thanks..  really useful diagram on the link you posted!

The sketch in this post shows the rodding layout for some double ended points including the directions of travel of the rods and compensation for temperature changes.

many thanks Ian..  this is exactly how I needed it explaining..  this is why i love RM Web!!

Both points 4 would have been connected to the same point rodding, and would throw together. The same for both points 6 and both points 14. A connection to the rod would have joined to an angle crank with a short rod across to the point on the run round loop, while the main rod continued to the second point and another angle crank.

 

The + signs by the points 6 and 14 on the main line denotes facing point locks (FPL) operated by levers 7 and 15. There is also a fouling bar by point 6 (denoted by the short parallel line) which would have stopped lever 7 unlocking point 6 if a train was stood on it..

Thanks for this info..  I sort of assumed this must have been the case..  I need to find a picture now of how the rodding would have been set up to enable 1 lever doing both points at the same time!

Safety is paramount. A short crossover would almost certainly be operated by one lever to prevent a train being directed via a properly set point onto an incorrectly set one. 

 

I am also fairly sure that facing point locks were used where there was the slightest chance of a train taking a point when the blades were facing the oncoming train. I think there was a speed limit on points not fitted with operational locks so slow shunting moves on such unfitted points were Ok. I think there was also a prohibition if any passenger servies were involved.

 

The best bit is that all modelling of point rodding is purely cosmetic anyway and is small enough to be purely an addition in any event. 

Hi everyone,

I need some help understanding how the point rodding would have looked/worked at Fawley in Hampshire.

I am modelling Fawley and for the most part I understand how things would have worked, however,  I don't understand how the point rodding would have worked for the points numbered '4' in the attached picture...  there is only a single run of point rodding to the 2 sets of points numbered '4' looking at the picture attached...  would the loop point have been clipped and the rodding operate only the platform road point?  Or would the single length of rodding operate both points on one pull of lever '4'?

Also is the symbol like a cross on the points labelled '6' a facing point lock??

Hopefully I have explained this clearly..  as you can see I am no signalman but I do want to get this right.

many thanks in advance!

Richard. 

thanks all for you replies.. very useful!

Hi,

I got my 00 Heljan class 33 out of the box last night for the first time in ages only to find that the destination blind glass had fallen out and is now missing.. 

is this something that can be replaced easily?  if so do Heljan keep them in stock or is it a case of pleading on the net trying to find one?!

Any ideas much appreciated!!
