Scale: 1/87 (H0). Printing technique: resin print. Design: Carothers & Randolph tunel portals USA Virginia. Randolph is in its original version, Carothers after reconstruction (widening). Dimensions:
With interior: x=180mm; y=98,5mm; z=117mm. Without interior: x=180mm; y=21mm; z=117mm. Files fit on the printer Anycubic Mono X. The tunnels are tight. Due to the different distance between the tracks in the H0 scale double-track line (than in the original), you'll have to place the tracks close together. An alternative is to place the portal slightly higher than in the original.
