When Lenz track was manufactured in China I'm told it had some commonality with Atlas track; now that it is manufactured in the UK by Peco, the rail at least is common with the Peco 143 -- you'll note on the Lenz website they sell Peco rail joiners !
I note from your past forum posts that you model modern North American railways [ at least in 3R ]; if that is the case here in 2R I would certainly suggest the Peco track with its Pandrol fittings -- superb looking. You can then use the Peco turnout -- again, a superb product in looks and operation -- supplemented by Lenz turnouts where space / application requires, such as double slips, curved, 3-way, etc.
If this is for a 3R application then the Peco track + Atlas 3R turnouts would be a good combination.
If you are buying used Lenz items, they may be from the China era and use different rail joiners, etc.
I hope the above helps.
Best regards,
