Hi all
I am thinking of doing a rally track soon
so reading all the rally treads and others alike .
Want to do a single track so could the new APB be used at start of track
and then use the other lane maybe passing over in other direction as the finnish?
kind regards ade

sure, but if the base is crossing both lanes, he'll count two laps at the end where the base is connected. That's why that other rally track design had the base only half on. But, it's not a big deal, really. Just set the base to twice the number you actually want to run.

Right, of course. Interesting, within a few weeks time I am going to make a single lane rally track, powerd with Sport World. Sport World has a special rally option that deals with single lane rally set up. I assume you will put the APB in analog mode ?

You can't put it in analog mode, as that will send power to the other rail, and the system will go into safe mode. If you're going to do it in analog, you should have only one side connected.
Actually, now that I think about it, if you do a typical rally loop with the APB next to a loop connected to both lanes, you'll cause a short, because the left rail of one lane will connect to the right rail of the other lane. So, in any case, with the APB and other digital bases, You should only have one lane connected, or use lane changers or pit lane sections so that the base lanes are only connected to one direction of the loop.

If anyone has done this in practice, I'd like to see how things worked out.

It works fine using a standard Sport power base, but by the jargon (which I don't understand) I assume you're talking about digital. As you you'd only use one car at a time on a rally stage, do you really need it to be digital?
I'll get my coat.........

It can't be done, well not unless you have an isolating joint. Otherwise you are shorting rail one to rail two and rail two to rail one so you will immediately go into overload.

Not that difficult to isolate a joint, I did one for the gadget shows attempt at the scalextric speed record at chatsworth. They needed an automatic brake section, so I removed the sticking out pin at each side of the joint (just pull with some pliers) and then I shorted the end section so that all cars would brake when they hit that section.

Do it on a joint that is cheap as it is not so easy to fit the pins back.

Do it anywhere in the loop. Power will be fed from lane 1 up to the joint on one side and from lane 2 up to the other side of the joint. Mind that you only want to take out the links on one lane at the joint that you isloate, the other lane needs to be still connected.
