The Mid Hants Railway reopened for services today with 4MT Mogul 76017 and Ivatt 2MT Tank 41312 in service. Next week will see 41312 replaced with the 2H DEMU Unit No.1125 - If you are looking to travel please note that until July all services will originate from Alresford and will terminate at Medstead & Four Marks.
The traditional way to do this is with cab control, with or without common-return (common-return simplifies the wiring a lot). Each controller has switches that can connect that controller to any section. PECO used to produce a very good pamphlet that explained this. Not sure if it's still available.
The only snag is that it's possible for more than one controller to be connected to a particular section at the same time, but that's a DDT (don't do that).
On another note............
I found an interesting layout on the DLS. <KUID:876170:100201>
So basically what I have is this.
Though it's a little odd because it's laid out on a long narrow set of boards with the M&GN line and the GER line to Hunstanton running parallel to each other. There is quite a bit of scenic separation between them though so it's not blindingly obvious. Overall though the M&GN section is well done. Quite a lot of M&GN railway buildings have recently become available and these were used on this layout to good effect. The GER side is still suffering from a slight BR Blue infestation and the Holy Inquisition is hard at work rooting out the last of it.
Overall though I think the layout is useable. The builder used an awful lot of spline tree and vegetation models to create the landscape which is something I don't like since they always look wrong and fake like painted cardboard stage sets. Splines also tend to be memory hungry. But I can replace those with proper vegetation models though. The layout builder also knew not a thing about blending ground textures, but again I can fix that; - it's just a bit tedious.
More than likely I'll end up attaching it to my present GER layout with the missing Kings Lynn bit a fiddle yard area hidden by scenery. Gradually it will be scenically converted to match my own methods, but what is there and useable tips the balance towards it being a worthwhile option for me.
