The cars are articulated and ride on modified AZL 90001 roller-bearing trucks. These trucks swing quite freely. A railing ramp is suggested for placing the cars on the track. A minimum of curve of 195mm and above is recommended. Each set will come with six containers. The 53' containers are the first time AZL has offered corrugated type containers in this length. The 40' containers are a rerelease with new tooling as well. AZL plans to offer a mix of containers from discount stores, online stores, overnight delivery services, shipping companies, moving companies and railroads..
