Title: Twin track controllers
Post by: Sioned Arrowsmith on June 07, 2017, 18:21
... when the tracks are independent and different in character (but sharing the scenery). Starting from nothing. And home-build electronics is out.

I guess "twin track" suggests a Gaugemaster D. The Morley controllers also seem to fit the bill: does anyone have any experience with them (http://www.009society.com/forum/index.php?topic=1843.0)? Although I'm a bit confused as to why the Vector is recommended for OO9 rather than the Vesta, when there are so many N-gauge donor chassis.

But given the tracks will be operationally different, is there an argument for having a pair of single-track controllers with different characteristics? (eg a Gaugemaster Combi and, er, something else.)

No reason, that I can think of.
You need to think about cost and what space you have to accommodate the controller(s) and (if separate) their power supplies/transformers.

However, I would advise you buy new, decent, controllers. It distresses me to see people with high-value, modern locos on their layouts with crummy controllers that look like something from a 1950's "B" sci-fi movie....

The Gaugemaster d controlled track outputs can be used with common return wiring as the two controllers use different windings.  This will significantly reduce the wires needed on a sectional layout and only single pole section switches are needed. However sadly the 16v ac output cannot be used with common return wiring as it uses the same winding as one of the controlled outputs. This will almost double the wires needed on a layout if you have electric point motors unless you have a separate 16v transformer to power them.

Gaugemaster controllers have a lifetime guarantee, all you need to pay for is the postage back to them.
The most common fault I have found over the years is a dirty control pot causing erratic behaviour as you turn the speed up and down. (The power light will also flicker when turning the speed up and down with no loco on the track with this fault.) But send the unit back and they will fix it and send it back to you free of charge.
In fact they will fix any of their controllers provided the parts are available and the unit has not been tampered with. So purchasing a second hand gaugemaster controller is a safe bet even if it is not working well.

I am  a  digital  user  HOWEVER  I  have  had  quite  a bit  of  experience of  both  GMaster D  and  Morley Vesta  on  N  gauge  & 009 layouts,  both  work  well  but  the  Morley in  my  opinion  has  slightly better  slow running  control  AND  value  for  money  is better  as   not   only  do  you  get  a twin track  unit  also  included  are  2 x Hand  held  controllers ( 2.5M cables)  which  plug in to  the  main  unit  and  a  CDU supply  for  solenoid  point motors  built   in  if  required!

The  Morley looks  a  little  more  refined  ( I am looking  at  one  as  I  type!!)

This might not be a problem at the top of anyones mind when purchasing controllers but if you are exhibiting then weight can be an issue.

A model D is quite heavy although they are extremely robust and the ones I have used have never failed. An alternative is two Model W controllers although each would require its own 16v AC supply. You pays your money and takes your choice.

But if you don't use common return on the controlled outputs, could you use it for the accessories and the controlled output they don't share a winding with? (I've got to say, I'm struggling to understand this -- O level electronics was a long time ago.)

Re  your  early  enquiry  why  Morley  recommend  Victor  for  00-9,  this  was  discussed  ages  ago  on  another  forum    and  the  answer apparently  was  that  the  description  author  had  mistakenly considered 00-9  to  be  a  variant  of  4mm scale  and  not a Narrow Gauge  system  using  similar Mechs  to  N  Gauge.

As  a matter of  interest  I  have today disconnected my digital  system  from  my  work in  progress 00-9 layout  and  borrowed a  couple  of Minitrains locos to  test  them  with  my  Morley  Vectis  and  Gaugemaster  D  I found  that  performance  was  nearly  identical  in  terms  of  very  slow  speed  running  ( we  wont  mention  top  speed!!!)  But  on  a  gradient  of  approx.  1  in  25  the  Vectis  gave a  better  slow  speed performance  on  the  climb,  descending though  showed  little  difference.

If you are building an exhibition layout I would think twice before using a "D" as you will have to make something for it to sit on and then you can only operate from one place...

A couple of Combis would work better I think...

It  distresses  me  more  when  I  read articles  in  Magazines  describing  layouts  etc  when   it  comes  to  the  power  supply  and  ANCIENT  Hammant  & Morgan   Duette  etc.  ( or other  ancient brand) is  mentioned,  its not  too long  ago  that  a  modeller was  electrocuted  when the  metal case  of  his  old  controller became  live  due  to  cable  wear!

It  surprises  me still that some  modellers  still  hang  on  to  old  controllers, when  a replacement with much  higher  spec  would  cost  less than  a  locomotive.

I tend to agree. It does stress the importance of PAT testing, especially the initial bit we can all do informally which is to inspect our gear for loose wires, worn insulation, signs of overheating and so on.

Clearly something was very wrong in the instance mentioned. If the live wire had come loose and was touching the metal case it should have blown the fuse. If a controller has a metal case that is not fully bonded to earth then get rid of it immediately.

People would rather save a few quid than play safe... There's no other logical reason as the new controllers are light years better than the old ones so no logical reason to buy old ones...

gaugemaster combi's for me. Economical, nice to handle and good running,

There is nothing stopping you not using common return wiring for the points and accessories. It will just need more wires on the layout!

If you do not use common return wiring on the controlled outputs every section on the track will need two wires from every section switch you have and every section switch will have to be double pole. This will effectively double the wires between the controls and the track.
Using the same common return for the track and the common on all the point motors and other electrical accessories on the layout will also save a lot of wiring.
