Hi All, This may sound an obvious question, but are there any guidelines on whether a turnout should be LH or RH? The reason for this rather basic question is that in my current plan for Wolverhampton Low Level there is a turnout on the down road that splits tracks going into the platforms with the other going to the goods avoiding lines at the rear of the station. I would think that the main route as it were would probably be in the direction of the goods lines as trains going through the platform roads would likely be slowing down more in preparation for stopping? I've attached a crude drawing to help with my explanation, hopefully it will make sense! Kind regards, Jim |

Hi Jim The road that takes the most traffic is usually the main road and the divergence is off of that. If however both roads are taking similar traffic I would think that the passenger rated line would take precedence over the goods only line. I hope this is of some use and others may know better in which case I will stand corrected. Cheers Phil  |

If you face the crossing nose and the point rail is on the right hand side, then (on the GWR) that is a right hand crossing. On other railways it would be a left hand crossing because the splice rail is on the left! | ||

Hi Jim, As Phil says, a passenger running line would always* have priority over a goods-only line. In this case that makes it a right-hand turnout in your sketch with the passenger line as the main road. If both lines are passenger lines, the one carrying the highest-speed traffic would normally be the main road. That may not necessarily be the one with the most frequent service. Also, if both lines are passenger running lines the turnout is likely to be a much longer size than for goods line connections. I don't think the presence of the platform is relevant here, unless it's a terminus station and you can therefore be sure that every passenger train will be approaching at very slow speed. *dangerous word, always. I'll leave some space here for the inevitable picture from someone showing the exact opposite:  Martin. |

But Jim is asking about the hand of the switch, not the hand of the crossing. The hand of a switch is the side to which vehicles are deflected at the planing angle. Vehicles taking the main road are not deflected, and can therefore run at full line speed. The handing of a turnout is normally quoted as matching the hand of the switch. regards, Martin. |
