Using the two Flickr images to give position, and the CRS track plan, here's a guestimate of what Nancegollan might have looked like. All suggestions welcome.😀

That looks pretty good to me. I have no idea why they added the extra loop, given it also required an extra road bridge, but it would make a nice model. Maybe it helped with goods traffic, so that there was no need to shunt traffic backwards into the goods bay? Certainly I don’t know of a realistic model of Nancegollan, but perhaps there is one out there somewhere?

Just noticed the CRS images show the loading dock has a distinct curve to it, so this might be better?

Do you think that is the grounded coach that is shown on the map?

It certainly could be.

With acknowledgements to K.Jenkin for this from the CRS page.

If it was old enough to be on an old OS map, what could it be?

Perhaps an ancient GWR clerestory coach like this?

Jenkin's photo shows just how complicated even the points at a minor place like Nancegollan could be - you are not going to be able to buy that combination of frogs RTR anytime soon!

You almost can!  It’s just a tandem turnout (asymmetric three way) with the following turnouts hard on the crossing nose.  Might manage something quite close with some point trimming.

Trying to do in 3m x 1m under bridge will be scenic break.

 

Sidings will be flattened slightly, considering a squirty plastic printer, and templot.

 

Will be shrunk, aiming for 4 coach platforms.

 

Clerestory i did have diagram Somewhere, may craft cut.

 

My parents both come ftom Cornwall,  one near Helford river , one near lizard..

 

Storage sidings will be under a BR layout.

According to Wikipedia there were extensions in 1937 and then again in 1941.

 

Thanks for mentioning that.

 

Quote

In 1937 the facilities were considerably extended, with a full crossing facility for passenger trains and longer platforms on both lines, as well as a loop line behind the up platform and a large goods yard - In 1941 the station's goods sidings were further modified and extended in connection with airfield construction in the locality, and a new signal box with a lever frame that had been relocated from the Cornish Main Line at St Germans. A second, metal, bridge was also built at this time to carry the road over the new goods yard access lines. A camping coach was positioned here by the Western Region from 1958 to 1962

I'd initially assumed the airfield was Culdrose, but curiously Wiki says that wasn't even surveyed until 1942.

Was there a seperate airfield at Goonhilly perhaps?

Other WWII RAF sites in the area were Predannack (Airfield) and Dry Tree (Chain Home Radar). 

 

Thanks, that gives the continuity to the expansion at Nancegollan in 1941. Presumably because there was more space available there than in Helston?

RAF Predannack was opened in May 1941 as a satellite for RAF Portreath.

Yes, Helston was built on a rather congested site and actually was not intended to be the terminus at all. The land slopes quite strongly around it and laying down extra sidings would not have been cheap to do.

Cury / White Cross / Cross Lanes.

 

Viaduct over the valley with stream going to Poldhu.

 

East side of Mullion, where it is flat.

 

Lizard would be possible as quite flat.

I wa sonce wondering if this could have happened so I worked out a rough route with OS maps. Mullion MAY have made sense, but south of there all smallish villages.

 

However Porthleven MAY have had enough traffic.

 

Coverack / St Keverne would have been doable, but again traffic.

 

 

Just found this

No where near Mullion, but the last bit I had more or less correct.

That is tight, the switch blade of the forward turnout (at far left) appears to reach back right to the check rail of the next turnout and similarly on the frog side. It's like they needed every mm of that siding length.

I think I may 3D print these as Peco Bullhead are very pricy.

 

But I need a squirty plastic printer as build be too small on Mars2 Pro.

Thanks for the mentions of the proposed route to the Lizard.

I have a vague memory of a scheme to connect to Penryn as well.

Was it via Gweek and Constantine?

There were a whole bunch of different schemes considered in this area of Cornwall. The various books describe them:

  • Hayle to Helston Tramway, not built, 1819
  • Tram line from Penryn  to Redruth with branch via Wendron to Helston, not built, 1825
  • The Hayle Railway, with proposed branch to Helston (branch not built), 1834
  • Helston to Penryn, via Gweek and Constantine - as per @KeithMacdonald sketch, not built, 1846

It seems it was the establishment of the GWR mainline to Penzance that finally tipped the balance and decided the route taken for Helston.
