Hi All,
I've put together a point rodding and signal layout plan for my new layout. It's based quite closely on Maghull station on the Liverpool - Preston line in the 1950's. The platforms sit between the level crossing and the yard entrance. I really knew very little about point rodding layouts and linkages etc. before joining the RM Web so I've gratefully gleaned much information from poring over the many previous threads here, over the last few weeks. Hopefully, the plan is fairly self-explanatory but a few questions remain:-
1. There was a ground frame at Maghull when the long-departed goods yard existed at roughly the point I've positioned it. I assume it's because of the distance from the signal box (SB) to the farthest exit from the yard to the main line (about 450 yards). Would it be necessary to run a rod from the SB to the GF to release it, or could this be achieved by a release key to be collected by yard staff from the SB?
2. If the Distant Ground Signal (GS) in the yard is correct, would this have been operated from the SB or GF ? It was about 250 yards from the SB.
3. From the plan it is clear that there are two crossings from the up to down main and the track into the bay, with a trap point, is effectively a crossing. The crossings will have occasional passenger movements so would have FPL's, but would the bay entrance, as this would be merely a shunting move of empty stock into it ? Also would the lay-by or either yard entrance require an FPL as this will be goods only ?
4. I understand now that with a crossover, one rod only is required from the SB to operate both points at once. Does the same apply to FPL rodding? (Please say yes.... !!!)
5. Finally, is it necessary to have a 'shunt limit' signal near the far left hand yard exit as I've put (SL)?
Any advice on these queries is much appreciated as is the advice you've unknowingly provided me with already!
Cheers
