Train Mountain Railroad is a large-scale model railway located in Chiloquin, Oregon. It is known for being one of the longest miniature railroads in the world, boasting an extensive network of tracks that span over 37 miles. The railroad is designed for the use of ride-on scale model trains, often featuring live steam, diesel, and electric locomotives. Train Mountain serves as a venue for rail enthusiasts to bring their model trains and run them on the extensive layout.

A 1:25 scale model means that the model is 1/25th the size of the actual object it represents. In other words, for every 25 units of measurement of the real object, the model is 1 unit of measurement. This scale is commonly used for a variety of model types, including automobiles, architecture, and dioramas.

A 1:285 scale means that one unit of measurement on a model or representation is equal to 285 of the same units in reality. For example, if you have a model vehicle at a 1:285 scale, 1 inch on the model represents 285 inches in the actual vehicle. This scale is often used in modeling, particularly for military models, buildings, and dioramas, where a smaller scale allows for more compact representation of larger objects or scenes.

A 1:35 scale refers to a scale model where one unit of measurement in the model (such as inches or centimeters) is equivalent to 35 of the same units in the real object. For example, if a model is 1:35 scale, and a real tank is 3.5 meters long, the model would be approximately 10 centimeters (or about 3.9 inches) long.

The Strengthen the Arm of Liberty Monument is a notable statue located in Fayetteville, Arkansas. It was created by sculptor Charles A. Wright and was dedicated in 1910. The monument commemorates the Confederate soldiers from Washington County who fought in the Civil War. The statue depicts a soldier representing the Confederacy, and it serves as a historical reminder of the region's involvement in the Civil War.

A heptadecahedron is a type of polyhedron that has 17 faces. The term "heptadec-" comes from the Greek "hepta" meaning seven and "deca" meaning ten, thus literally translating to "seventeen." Heptadecahedra can have various configurations based on how the faces are arranged and the types of faces used.

The compound of five great cubicuboctahedra is a complex geometric structure formed by the intersection of five great cubicuboctahedra, which are Archimedean solids characterized by their combination of squares and octagons in their faces. In geometry, a compound involves two or more polyhedra that intersect in a symmetrical way. The great cubicuboctahedron itself is a convex polyhedron featuring 8 triangular faces, 24 square faces, and symmetrical properties.

The compound of four octahedra is a geometric arrangement or polyhedral compound formed by combining four octahedra in a specific way. When arranged symmetrically, these octahedra can interpenetrate each other, creating a complex shape that often highlights the symmetrical and aesthetic properties of polyhedra. In three-dimensional space, an octahedron is a shape with eight faces, each of which is an equilateral triangle.

A compound of twenty triangular prisms would be a three-dimensional geometric figure composed of twenty individual triangular prisms combined in some way. A triangular prism itself consists of two triangular bases and three rectangular lateral faces. To create a compound of twenty triangular prisms, you can arrange or connect these prisms in various configurations. The specific arrangement and properties of the compound would depend on how the prisms are oriented and connected.

Disphenocingulum is a genus of extinct reptiles that belonged to the group known as parareptiles. These creatures are characterized by their unique skull structure and dental patterns. Disphenocingulum lived during the late Permian period, which was around 260 million years ago. Fossils of Disphenocingulum have been found, providing insights into the diversity of early reptiles and their evolutionary history.

The elongated pentagonal cupola is a type of convex polyhedron and a member of the Archimedean solids. Specifically, it is formed by elongating a pentagonal cupola through the addition of two hexagonal faces on opposite sides.

The elongated pentagonal gyrobirotunda is a type of convex polyhedral compound classified within the broader category of Archimedean solids. It belongs to a group of shapes known as the gyrobirotunda, which are characterized by their symmetrical arrangement of pentagonal and triangular faces. Here are some key characteristics of the elongated pentagonal gyrobirotunda: 1. **Faces**: This solid has a combination of faces, specifically including pentagons and triangles.

The great triakis octahedron is a type of Archimedean solid, which is a category of convex polyhedra characterized by having regular polygonal faces and uniform vertex arrangements. Specifically, the great triakis octahedron can be described as follows: 1. **Face Composition**: It consists of 24 equilateral triangular faces and 8 regular quadrilateral faces. The triangular faces are arranged around the edges of the octahedral structure.

A Noble polyhedron is a type of convex polyhedron that possesses a high degree of symmetry and a well-known set of properties. Specifically, they are characterized by having regular polygons as their faces and being derived from regular polyhedra through certain symmetrical operations. Noble polyhedra are defined by their dual relationships with regular and semi-regular polyhedra, exhibiting uniformity in the arrangement of their vertices, edges, and faces.

An octagonal bipyramid is a type of polyhedron that is classified within the category of bipyramids. It is formed by connecting two identical octagonal bases at their corresponding vertices.

The term "parabiaugmented truncated dodecahedron" refers to a specific type of geometric shape, which belongs to the family of Archimedean solids. To break it down: 1. **Dodecahedron**: The regular dodecahedron is a polyhedron composed of 12 regular pentagonal faces, 20 vertices, and 30 edges.

A pentagonal antiprism is a type of geometric solid that belongs to a family known as antiprisms. It is constructed by taking two pentagonal bases that are parallel to each other and connected by a series of triangular faces. The triangular faces are arranged around the sides of the bases and are oriented such that they provide a twist between the two bases.

A rhombic icosahedron is a type of polyhedron that has 20 faces, with each face being a rhombus. It is a member of the class of Archimedean solids and is characterized by its symmetrical shape and uniform vertex configuration. Here are some key features of the rhombic icosahedron: 1. **Faces**: It has 20 rhombic faces.
