I’m a little late to this thread but I’ve been using superstreets for many years now and also have installed a few of those Bachmann E-Z streets switches (turnouts) which I control with a TMCC CAB-1.
Regarding hook up wires, as Gun Runner John would say, you can “roll your own”. Use your own wires crimped into 18-22 AWG female push-on solderless terminal lugs available at electronic parts stores. You will have to also crimp the ends of the lugs slightly to enable them to stay onto the built-in terminals on the underside of the track. If you still have a Radio Shack store near you they may carry those lugs.
One issue I haven’t seen mentioned in this thread is that Super Streets and its successor E-Z Streets so far only come in two curved track diameters: D-16 (16” outside diameter but only 14 3/8” actual center-to-center rail diameter) and D-21 (21” outside, 19 1/8” cr-cr). Not all vehicles, especially certain trolleys, will negotiate the D-16 curves.
Another issue is noise as I would recommend using something under the plastic superstreets track to deaden the sound. I use kitchen cabinet shelf liners. Re the screws to use, I also use a #4 screw but make sure they have flat heads so that the manhole covers will fit flat in their receptacles.
And one other issue is trying to control multiple vehicles on the same track. While it’s a big step forward toward realism to be able to run one electrified vehicle by itself on a surface that looks like a city street, sooner or later you will want to run more than one at a time on the same street. I have done this with MTH Railking PCC streetcars using the K-Line superstreets 10” insulated rail sections and relays. But the automobile-type vehicles are usually too light and have such small diameter wheels that they don’t make good-enough electrical contact with the insulated rails to trigger the relays. In addition whether they have traction tires or not, they often lose ground on the insulated rails and completely stop. Quite some time ago “Dale H” posted a message on this Forum proposing a way to run multiple vehicles using magnets and reed switches to detect the vehicles and trigger the relays. I believe he posted a follow-up message explaining how to do that so check the archives.
