For the individual cars, they come in nine different body styles. Three of the cars are heavyweight passenger cars (like usual). The the rest of this month's offerings are freight cars including another Husky Stack well car. Four of the cars are 020 series PS-1 box cars in United States military livery. Three of the cars are from collectible series: Friendship Train, Ringling Brothers Ad Cars and HJ Heinz reefers.
Runner pack #136 is now available. It is a set of Santa Fe covered hoppers.
Of particular interest are the six new diesel switchers. Three are in Southern Pacific 'Bloody Nose' livery. One is meant to pull the 'Nasa' series cars, and the last two are undecorated.
The containers are 53' Corrugated unites decorated for the UMAX container line.
Pre-Orders: Runner pack #141 was announced for delivery in June 2018: four Missouri Pacific Despatch Stock cars. They also announced a Cotton Belt heavyweight passenger 5-pack. The final offering was two more of the Ringling Brothers Advertising cars. These will be delivered in June and are the final two of the six-car series.
