This probably isn't going to be solved without either changing to remote controlled PF trains or creating a complex control system. Even if you were able to supply the exact same constant voltage to both trains, they'd both need to have precisely the same motor characteristics, weight, and aerodynamic properties. That's going to be difficult. One way to ...

I just got two new 8885 remotes. Neither was working. Turns out in my case the plus terminals and the plus side of the batteries were not touching due to the terminals being kept too far away by the plastic housing. I bend the terminals a little by inserting a small screw driver behind them and now it works as a charm. Better to take batteries out when ...

It basically forces the coupling magnets to separate via the pins pointing downwards from the magnet holders: Here's a demo.

To add to the excellent answers already provided, the cheapest LEGO train set currently available giving you a full oval/circle is 60051 and costs $149.99 in the US Lego store. You might be able to find it slightly cheaper on Amazon.com (currently $127.21 in the US) or ToysRus.com (currently $149.99 so same as LEGO store) sometimes. The equivalent purchase ...

Each piece of flex track is equivalent to 1/4 piece of regular track. The standard train curves are 1/16th of a circle and thus an oval shape is not possible, however, with 64 pieces of flex track you could make an oval by squashing the circle a bit. 7499 comes with 16 flexible tracks, so you'll need 4 of them to make a regular train circle. The flex track ...

The flexible tracks are not designed to make a full oval, but to add subtle, smaller curves in a train layout, using just a few at a time. If you do use too many flexible tracks next to each other they will slow down your train, they are very noisy, and can even derail the train. Here is an excellent comparison video between the regular curved tracks and the ...
