The first items of ready-to-run rolling stock in TT:120 scale from PECO are now available, representing a mixture of the post-grouping companies, British Railways and the first three private owner liveries.
TT:120 is the first British "true-to-scale" scale - 1/120 scale models running on 1/120 scale/gauge track. 
These new 7-plank wagons feature the highest standard of manufacturing you would expect from PECO:
Fine plastic moulding with thinner wagon body walls for accuracy.
Interior detail as well as a high-level of exterior detail
Separately-fitted brake lever.
Brake shoes in line with the wheels
Ultra-fine printing detail
Free-running metal-tyred wheels
Standard (removable) TT:120 coupler compatible with other TT:120 rolling stock on the market
