A must have for 00 gauge railways with models of third rail electric trains
The conductor rail chairs are very fiddly, threading them onto code 60 rail, but the final result is well worth the effort. My own layout is based on the Southern Railway which currently has a great range of stock available, but these chairs can also be used for the London Underground 3rd & 4th rail system. Make sure that you buy plenty to allow for extensions and losing some under the bench!
