This pack comes with the mooring point A, Mooring point B, Tyre chain and chain link fence models. Some models are in both 00 gauge and N gauge and some just scaled for N gauge depending on the needs of the model for printing. 
 
For models with only an N gauge model: for TT:120 the model can be scaled by 125% and those modelling in 3mm can scale the model by 150% and those in 00 gauge can scale by 200%
 
For models with both 00 gauge and N gauge: for in TT:120 the N gauge model can be scaled by 125% and those modelling in 3mm can scale the 00 gauge model by 75%.
