Modeling SP #137

SP #2300 had a short life so would have also been painted SP Olive Green with a black roof and Dulux Gold lettering.

SP #138 received SP Lark Dark Gray paint on its conversion to Crew Car.

Walthers make the perfect car in HO Scale, once available painted for SP, if it is still available, it will probably only be in undecorated.

Modeling #2300 could be a bit of a challenge; unless a brass 60-C-4 has been made... one possibilty that may come close, is to take one Athearn Standard Diner and remove around 5 feet from the length and then replace the roof with a shortened one from an Athearn Standard Round Roof Coach. Overall length over diaphragms needs to be 67' 8¾".

For the later #138, Union Station makes 4069H Laser-cut styrene sides to fit a Train Station Products P-S Car core kit it requires other parts and trucks/couplers to complete.
