This download includes both .STL and .STEP files for NCDOT Baggage/Lounge cars (RNCX 400201-400205) both in early and later modified versions, as well as a 56-seat coach (RNCX 400008-400012). The prototypes are pre-Amtrak era cars rebuilt by Delaware Car in the mid 2000s. To complete these cars as seen in the photos on the Project Gallery, you’ll need both FDM and resin printers. You’ll likely be able to print everything with a smaller resin printer if you slice the parts into multiple smaller ones that fit in your printer’s build volume.
