I did make a few small changes in the track during the past year or so. One of the bar stools fell apart so I bought new ones with padded seats that are color coded to match the lanes, I stole that idea from the famous Area 51.
I also added color coded plaques for the driver's stations and the house controllers are color coded as well. There are now XLR connectors along with the original screw post controller connections and the fuses have been replaced with manually resettable circuit breakers.
There is now a pair of amplified speakers mounted under the driver's stations and I replaced the old Lambda power supplies with a pair of 20 amp Mastech supplies.
