I am currently in the process of drawing up a track plan for my new layout based upon Cheddar station. Still need to do the fine editing of sleeper positions etc, but would welcome any comment on areas to fix/improve. This includes my first attempt at drawing a single slip. |

Good attempt but there are a lot of REA B6's and it looks as though you have the room, in over 12 feet length, to do GWR 10 & 12+ foot switches, They would look better for a GW layout and have the correct timber spacings too. Did you follow a plan for this? You have also ommitted to shorten the check rails for your slip on the slip road side. Real, Customize V-crossing, half diamond check rails, shorten turnout road for single slip. | ||

I've now rectified the slip check rails, thanks for pointing that out. Regarding the GWR template types, In Templot I see two versions (GWR B which looks very similar to the standard one, and the 10 and 12 etc mentioned. Which of the numbered GWR points are comparable to the B6s I have used so far? As for the plan, its working from a drawing of the prototypes track plan, with a reasonable amount of selective compression (along with loosing the lower 3 sidings) in order to get it into the 12ft I have available. |

The era are you modelling will depend on the switch type you can use, certainly all the yard turnouts will use GW old type 10 ft switches. The GW flexible switches were not introduced until the 1920 and so would not have been cascaded down to branch lines until the mid thirties at the very least. The turnouts at Cranmore on the East Somerset Railway still have GW old type switches in place. The only new turnouts are on Network Rail in connection with the quarry traffic which are in flat bottom. Also GW check/guard rails are shorter than their BR REA counter parts only covering 4 sleepers. Have a look at GWR switch and crossing practice by David Smith available from the Great Western Study Group. Cheers Phil |

Changes have now been made to get GW 10s in the yard and GW 12s on the through line, Is there anything GW specific that would need to be changed on the single slip? Updated file now attached. Thanks for the help so far. |

Looking good all you have to do is shorten the checks by about a sleeper.  Cheers Phil |

There is one more thing I am struggling with, the check rails on the diamond opposite the slip are fouling the inner slip rail. I see in the manual something about changing the K check rails, but I havent managed to get results. |

Hi Rich Rich Pedder wrote: There is one more thing I am struggling with,I have had a look at your single compound and there is not much interference between the K checks and the slip road. I this case the GW would plain about 1/2" off the top of the corner of the check. See the attached photo. 38_021138_430000000.jpg  The little red circle at the top towards the left shows a little bit of the planing. The photo was taken for the chair rather than the check rail.

Just to explain, that's done so that as the slip road running rail wears down, the outer edge of the wheels will not catch on the nearby check rail. Check rails don't wear on the top, so they eventually stand proud of worn running rails. The machined off corners can seem puzzling when the track is new.  regards, Martin. |
