There is only one width of Carrera track. It is used in both 1/32 and 1/24 track sets. So, if you purchase a 1/32 analog or Digital132 set, you have the same basic track as in a Digital124 set. There is only one category of Carrera track marked STRICTLY digital. and another one marked STRICTLY analog. Other than that all their track pretty much works on Carrera 1/32 analog, Digital132, and Digital124 sets!
