I would like some thoughts in regard to a proposed Fiddle yard control method on my Wigan Wallgate layout.
I am using an NCE Powercab with a 5A booster for control of the layout, a full lap of the layout runs to approx 275' and so far the 5A supply runs three trains with apparent ease (I haven't plucked up sufficient courage to attempt anymore at this stage, keeping track of three on my own keeps me on my toes !)
The Fiddle Yard / Storage area is actually 2 parallel tracks of around 35 - 36 feet in length each that are located under the main board level. They have been layed with 3 isolating sections of roughly equal length giving me the capacity of holding up to 6 full length trains, ( there is also a similar arrangement on the other side of the layout )
My proposal is to follow a 'cascading' principal as described back in 2005 on a layout titled Lakeside my a chap whose name I appear to have lost, however.
The principal of operation is to 'call on' the train in section '1' either by manual, timed or Section ahead clear method, when that train has cleared an appropriate 'Train detection point' the train in No 2 section would be called forward into section '1', stopping at the appropriate position by the activation ( or deactivation ) of a relay to switch the power to the track off. At this position the train in section '3' would be called forward into section '2' position, leaving section '3' clear for the next arrival from Wallgate.
As there are 2 parallel tracks relays could also be used to alternate the settings of the points to call trains through in a varying sequence if desired.
The rationale behind this is to allow me to carry on such shunting operations as required with varying trains arriving at various intervals.
The Question : Does anyone see any issue as far as the controller and or locos are concerned with the track power being switched off / on in these areas.
Given that the power would still be on to the rest of the track and
when switched back on the trains would attempt to return straight away to whatever speed they were doing before stopping.
I currently have installed an isolating switch and fuse between the track and controller mainly because an unsighted short last week resulted in the fuse on the 5A booster blowing given that the booster is on the supply side of the controller I didn't like the idea of blowing things up.
As I run Wallgate by myself and I, the hand control and any 'incidents' etc always appear to be on opposite sides of the 20' sq room I will also be installng a series of 8 Emergency stops at appropriate positions around the layout ( A principal dating back to my 30 years looking after automatic molding lines in a foundry, and why I am proposing to use such antiquainted technology as relays! )
Thank you in anticipation
