Peco Turntable Motor

Recommended Posts

Amongst all the excitement over the newly announced Peco Bullhead track, no one seems to have picked up on the fact that they have also announced a new turntable motor, or was I dreaming........

Yes, looks interesting with, if I read it correctly, 8 exit positions.  It could be very useful under some of the nicer etched tables, London Road for instance, or even with the venerable Airfix/Dapol offering.

Not only that, but they mention retooling their own turntable slightly so that this is a clip fit - I know that the purists might want a different turntable, but at least Pecos is based on a British prototype, unlike, say Fleishmann - I think Pecos is based on an SR one?? - but, a simple to fit together indexed turntable: no contest, I'm having one!

Hopefully there will be some way of securing to an existing turntable, maybe by drilling holes and bolting. That would enable it to compete with the existing motorising kits. I use the ancient motor and transparent plastic gear box advertised for decades in RM - very noisy and reliant on sight for alignment. I'm wondering if the 8 exit positions are fixed or adjustable, and is this in addition to a complete (reverse) turn? Otherwise just 4 positions might count as 8 exits!

A simple non motored alternative might have been nice, and probably cheaper. The assumption that everything has to be electrically driven is short sighted, unless you are targeting mainly DCC supporters.

On a similar idea, how about re-introducing the r2p signals that Ration did for a while. The simple mechanism did not suffer from motor burn out. They also needed less depth under board than the Dapol ones.

Hopefully, this might lead on to an expanded range of turntable kits. e.g. a 60' version which would look more at home on a small/medium sized layout.

 

Then I can stop hunting for one of the smaller (70' in HO) Heljan ones........

I welcome this announcement. I am toying with the idea of a turntable on my next layout. If Peco do a british-outline one that is easily motorised, that could just swing it for me.

 

I know there are after-market solutions for the existing Peco TT but an all-in-one solution would be welcome.

Has there been any update on when this motor will be released? I purchased the peco turntable for my new build layout hoping it would be available fairly shortly

Did this item ever see the light of day?  it is variously listed as "TBA" and "discontinued" on various websites?

I have one and it is a very nice kit, as far as I am aware, still available.  Information about motors, noise and fitting them, is discussed here  https://www.dccconceptsforum.com/post/mister-rustys-workbench-dcc-peco-turntable-control-9914890?&trail=30 

 

These are not the only options, of course, but if you turn the sound on with the video comparisons of the motors, you can get a good idea of what might suit you.

 

One of the important topics mentioned is the turntable sagging with locos placed on the turntable.  I found a small amount of flash along the floor joins [it needed a magnifying glass to spot it] which left the walls and the top lip with 3 small gaps.  The gaps prevent the continuity of the circle formed by the wall and top lip, removing the structural integrity and strength of the intended circle.  Any appreciable weight on the Turntable would allow these gaps to close together, which, in turn allows the walls to partially collapsed inwards, hence the floor of the turntable sagging.  With the flash removed, the sides fit together and form a strong structure, which will take the weight of a loco with ease.

 

Hope this is of assistance.

I went with the MERG turntable controller with geared stepper motor, 16 positions and each one individually adjusted, it's not cheap at around £80 plus the turntable but it works well with very accurate positioning.

Thankyou both. I seem unable to press the thanks button at the moment.

 

I will check out both options.

The Peco motor is featured in their 2019 newsletter marked as in progress and with a modified design, so presumably is still planned for release.

Hi,

Also mentioned very briefly in the March '19 Railway Modeller, subscription copy arrived today:

Development work continues...

My dad spoke to Peco at Model Rail Scotland last weekend, he got the impression that it'll be released fairly soon. Seems they had some trouble developing the control to stop it in the right place, but that they may have removed that feature from the final product. (It was originally meant to have several preset stopping points.)

As a sort of aside, I do rather wonder about the desire for Indexed control for a turntable.  We do all sorts of things to make our train sets look, sound and operate like the full size versions {apparently made as prototypes for our 1:76 inadequates}.  Where turntables are modelled, there seems to be a wish to control them with a system which wasn't anywhere like typical of the full size ones.  Turntables were variously powered by human muscle, Loco vacuum, Loco steam, external electric / IC {?} motor etc.  The decision about where the turntable stopped was, in all these cases, a decision made by the operator.

 

Also, Indexing sets the Bridge rotating at a set speed, until the expected destination, at which point it stops just as abruptly as it started.  That would hardly have been how a large Bridge, containing an even heavier Loco, might have commenced or completed it's traverse.  Indexing seems an expensive way to replicate operations that were not typical of how they were achieved on full size versions.

 

Regards

A sufficiently clever controller could have realistic-looking acceleration and deceleration, if the developers decided that it was a feature worth incorporating. Any decent motor controller does it anyway, simply because for all but the least demanding applications starting full speed and then stopping abruptly is a good way to destroy the gears!

Indeed so, I'm well aware of means to introduce acceleration and deceleration, after a single accessory selection and have a full set of DCC Concepts details on how, thanks to Richard.

 

However, the bridge will still go at a set speed, regardless of load.  All of which has nothing to do with the point that Indexing was not like the methods the full size turntables used.

Just to be clear, Indexing doesn't replicate how the full size ones were and still are operated, but if you want to spend time and money Indexing, rule No. 1 applies, enjoy.
