As a train negotiates a curve, the force it exerts on the track changes. Too tight a 'crest' curve could result in the train leaving the track as it drops away beneath it; too tight a 'trough' and the train will plough downwards into the rails and damage them. More precisely, the support force R exerted by the track on a train as a function of ...
Standard Gauge, also known as wide gauge, was an early model railway and toy train rail gauge, introduced in the United States in 1906 by Lionel Corporation. [1] As it was a toy standard, rather than a scale modeling standard, the actual scale of Standard Gauge locomotives and rolling stock varied.
In track geometry, the horizontal layout involves the layout of three main track types: tangent track (straight line), curved track, and track transition curve (also called transition spiral or spiral) which connects between a tangent and a curved track. Curved track can also be categorized into three types. The first type is simple curve which ...
OO gauge was quickly eclipsed by the better-proportioned HO scale. The Lionel range of OO used 19 mm (3 ⁄ 4 inch) track gauge, equating to 57 inches or 4 ft 9 in – very close to the 4 ft 8 1 ⁄ 2 in of standard gauge. There is a small following of American OO scale today.
Before the Maxim joint venture, Lionel had partnered with Learning Curve to create the "Great Railways Adventures" series of battery-powered trains that were compatible with Brio-style trains and track. A specialized plastic track that snapped together was used in place of the traditional peg-and-hole system, although adaptors were sold with sets.
O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling.Introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s.
Also in 2007 Lionel started to sell American Flyer track, the popular 19" radius curve remaining unavailable to this day. In 2008, Lionel released an American Flyer Big Boy with TMCC and Railsounds. The license to manufacture the track had been held by Maury Klein, whose K-Line brand of 0 gauge trains competed against Lionel in the toy train ...
