I am working on designing a triple Kato Unitack loop, but I can't find the Kato HO Unitrack interchange crossover track pieces in the database, such as the HV4 being 3-114. Any idea why this is? Or do I have to create one using basic turnouts?
Kato Unitrack HV4 looks like a set of individual tracks -
do you have the individual part numbers of the articles in the set?
