My tracks can be Atlas,and Peco in flex track sections
My diamonds are in Atlas track and all my switches are Peco,exept one that are an Atlas,but I will replace it very soon by a Peco
Atlas switch are a bit fragile and sometime,the blades does'nt hold on the moving part and make derail a train or cause dead spots and trains may stop on it,cause no power contact. Bachman switch are kind reliable,but not realistic like most on peopples would like to have and track section may give restrictions sometime,especialy with E-Z Track system,but they can give a solid base for running a train..
Atkas track section and flex track are easy to work with,holes are already made and only have to nail the tracks in place and you can cut a flez track section,to get the cuurve and the lengh you need
Peco track are same as Atlas,in section and flex track version..no holes are done in flex track,but I'm not sur for regulr section,if holes are made on or not..
Flez track are very easy to work,you need a curve,just do it,the flex track will stay with the curve on,without nailing it,with Atlas,you have to hold it in place with pins,before nailing them..
Wath I can recommand....you need a smooth running,you have the choice with Atlas or Peco..
you want to ear the clic clack from the wheels,you have choice with Bachman,Peco and Atlas track sections
you can still use flex track system,and make noth on rails,to make the click clack sound from the wheels
And finally..Rapido Trains made bendy tracks,very realistic,a bit more expensive but,a little bit fragiles,but very nice for full straight sections
