A share and show. I lasted posted something in 2010 in P4 while I was exploring feasibility and gaining confidence in my OS1250 map. Paul Boyd pointed out quite correctly that to get a layout of this complexity in EM would require a re-draw. So this is the EM version, work-in-progress. I shall attach the map as a bit-map after this. The copyright date was 1960, so to respect the 40-year rule I couldn't attach it last year. Now it's 2011.... The area which caused the greatest headache was/is the sort-of scissors affair in the bottom-left quarter. Particularly with regard to check-railing on one of the turnouts. This is one of those instances of a tricky layout which was probably a challenge in full-size; and where P4 is better off than EM. Geoff Luckhurst |

This can move the crossing noses sufficiently to allow good checking. The change doesn't have to be large to get a crossing nose moving a significant distance. Jim. |

Jim, Thank you for that idea. I'm a bit of a purist at heart and resist compromise ! ( but then I adopted EM ! ). I had considered making the offending turnout with a moving frog. Regards, Geoff |

Geoff, Another thing you can try, if you don't want to change the track centres, is to make the crossing slightly non-symmetrical by moving one of the crossovers in relation to the other, which re-arranges the positions of the crossing noses and can sometimes make the checking better. Jim. |

Jim, Thanks for your interest. I may well have to try that. Again. You don't know how many times I've been round the loop. My source is the OS1250 map from 1960. Better than nothing but the line thickness creates an uncertainty. I have a 480-scale LNWR drawing from the time when the trackage was widened from 2 to 4 running lines. My drawings show a carriage-shed with only 3 roads and a different path for the left to right path through this "scissors". At that stage their drawing shows an outside slip associated with the 1 in 4 diamond further up. This LNWR drawing I have must represent a stage in the development. When the shed requirement became 4-road the outside slip became unworkable and this "scissors" became the least bad solution. Regards, Geoff |

Quite impressive; I'd be inclined to gently curve the fairly straight lines along the top of the plan to get rid of the train set look of going from nearly straight to sharp corner as I've done on my layout. If I knew how to download the plan, I'd do so! |

"Roythebus" Thanks for looking at my Rhyl effort. I agree with you about the "trainsetty" curves. I agonised about this for a long time until I realised that the normal viewing position will be the same as it was when I was a trainspotter in the 50's and 60's: from the car/coach park ( centre-bottom). I did have a go at uploading the BMP file but I must have messed something up; so you don't have all the full picture. The tracks on the left all pass through a bridge ( Vale Road Bridge ) and hence the 3ft curves will not be seen because the back-drop will fall just behind the bridge. On the right there is the carriage shed. In reality this was a straight monster about 560 feet long but I will show some of it ( the front) and the rest will be suggested to pass through the backdrop. The shed is/was about 30 feet high. So trains from left to right will emerge from the bridge and disappear behind a shed. My other reason for keeping the scale bend ( about 100 chains ) is the complicated trackwork in the foreground: the double-slip, the diamonds, the outside slip and the perverted scissors arrangement. These are all crushed close in reality. I'm not convinced they would survive being scrunched. I will post one of my photos taken in 1974 from the Vale Road bridge. The normal viewing/operator position would be where the road-coaches are on the right. By this date some of the trackwork has been stripped-out. Regards, Geoff |
