Ryan,

Why would you want to put a diesel with a cab at each end on a turntable?? If your Class 60 is a Hornby it is a good 10-15mm shorter than their longest steam loco all of which fit onto the Hornby turntable.

I initially installed a Peco but there were two problems, first the bridge seemed to float, after several attempts it improved slightly but there was still a 1 to 2mm drop to the joining tracks. I fitted a Frizinghall motor but no matter how slow it went I only succeeded in aligning tracks about 60% of the time and there was no hope of my 5 year old grandson getting it to align exactly. I looked at the Fleischmann but discounted it on the basis of the weight and cost of getting it to this part of the world. Freight would have added a lot to what is already an expensive item.

So I have finished up with the Hornby. Despite the "toy" appearance on the box it actually does not look too bad when hacked around and weathered.

I have not finished the loco yard yet but have installed the hornby turntable, hacked off the plastic edging and wired it for DCC operation. I used some balsa wood scribed to look like planks then painted with wood stain and weathered with "coal" marks etc and used in between the track and to the side of the track on the bridge. The fencing I have scrapped a little and put a slight bend in a few of the horizontal bars to look well used. The well was painted Tar colour sprinkled with talc before it dried. Other parts have been painted with a combination of matt greys and Humbrol gun metal. The raised area where the little hut is now has a card top and painted to resemble weathered concrete. Have not decided whether to keep the existing hut or scratch build another but the existing one with a bit of weathering looks a lot better than it did.

The whole lot is sunk about 15mm into the baseboard so the joining tracks are all on the same level as the bridge. If left in the original state on a flat baseboard there is an unrealistic slope up to the bridge. I have 6 tracks leaving the turntable, one still to do. With 4 of these I have used the small pieces of track which Hornby supply, with the support under one end cut off. With the 5th I have aligned Peco Code 75 right up to the bridge.

At present operation is still analogue but I may fit a chip later and have it under DCC control.

On the whole I am pleased. Tracks line correctly every time. On the negative side the bridge stops at every exit point including those not in use and the motor is a little noisy but not as noisy as the Frizinghall one. The other down side is that the exit tracks are built for set track geometry so if you want a couple of parallel tracks to go into say an engine shed you are going to have set track "6 foot ways". I overcame that but having a large radius Y point leading straight from one of the exits.

As mentioned I still have much to do to finish off the loco yard, but will take some photos and post once it is complete.

QUOTE So if I understand it correctly, you've got Hornby's turntable, but it stops on every exit?

Yes


QUOTE And to make it DCC, you must put a chip on the downside of your turntable? (Cause I'll don't think you'll place the chip on the upside. )

The motor is under the little house in a raised area to one side of the Turntable. As I am still using on analogue I have not chipped, but there seems plenty of room to install a chip.

QUOTE Is there any real benefit to dcc control of a turntable?

As mentioned I have mine under analogue control using a redundant Hornby controller with the speed set at about one third and an on off switch on the control panel.

The only advantage I can see of having under DCC control is that I would not have to go to the control panel to turn it on or off, but then as points are also under analogue control I have to go to the control panel anyway!!
