Dave, look at the picture of Selhurst I posted earlier.

Here it is again.

You will see alongside the switches of the points there is no conductor rail. This is what normally happens. This is what happens where trains run over at speed.

The shoes will drop off the sloping end and than ride up again when the rail starts afresh. The ends of the conductor rails are bent down to make this as smooth as possible. Rails may also swap sides to reduce the gap from one to the other.

However where speeds are very low a side ramp may be attached. This is only used where speeds are about 15 mph or lower.

I hate the job of fitting conductor rail. I wish a manufacturer would supply track with a third rail moulded on. I found the Peco insulators are very weak and once the third rail is dislodged it is very difficult to refit it. An article in Hornby magazine a while ago suggested an alternative method which involves soldering panel pins to the third rail. Bear this method in mind when it comes to short sections at points.

OO gauge models only have dummy electric shoes which do not touch the conductor rail. It is possible to fit sprung shoes which can be used to collect additional current on a DC layout. For more information see:-

Something like that for the end of rails, that's DC working it out for DCC wouldn't be that difficult but the speed of the train would alter the brightness of the arc, the Class 71 and 73 had the distance from the front pickup shoe the the rear pick up shoes about the same, for helping with this we will say its 35', foot crossing were ok but road crossing were always a bit bigger say 38' what this meant to class 71 was the booster dropped out it cycled down then back up took about a minute, the class 73 had a different system it applied power from the 3rd rail straight to the axle motors via a bank of resistor (30 i think)so it gave a much better arc the slower the loco moved the better the arc, when travelling fast it lost power and the normal way the driver would be to notch down(4 notches) if it was in weak field (full power with reduced winding's on the motor) other wise it gave a severe jolt, this made them very arcing in the snow or when there was ice on the 3rd rail...

That will do......little bend.......Next you need to learn how to "paddle up" to isolate a unit from the 3rd rail, your love it, playing with 750v and a piece of wood......

Dave you could bring the ramp nearer the points, all you need is a gap at the point where the shoes of any train coming off the curved route might hit the side of the conductor rail for the straight route and vice versa.
