HO Single Track Tunnel Portal - Concrete (2 per pack)

厂商原文

Cast concrete tunnel portals such as this are a common sight on railroads across North America.  Bachmann SceneScapes® tunnel portals are designed using true-to-life dimensions scaled to comfortably accommodate larger rolling stock, such as intermodal well cars with double-stack container loads, as well as track raised to an authentic mainline roadbed height (as found on Bachmann E-Z Track® and other track systems) . Tunnel s can be configured with or without the included side supports (abutments) as appropriate to your scene. Retaining walls are designed and scaled to work in conjunction with these tunnel s, matching their style and appearance, but can also be used independently to suit your railroad or diorama.
