Cape gauge (1,067 mm) Standard gauge (1,435 mm) Russian gauge (1,520 mm) Five foot gauge (1,524 mm) Irish gauge (1,600 mm) Iberian gauge (1,668 mm) Indian gauge (1,676 mm) This list presents an overview of railway track gauges by size. A gauge is measured between the inner faces of the rails.
Gauge boson. In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. [1] [2] Elementary particles whose interactions are described by a gauge theory interact with each other by the exchange of gauge bosons, usually as virtual particles . Photons, W and Z bosons, and gluons are ...
The anode is the electrode at the bottom. A Crookes tube (also Crookes–Hittorf tube) [1] is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes [2] and others around 1869–1875, [3] in which cathode rays, streams of electrons, were discovered.

The 37.5 mm length is not derived by a certain scale ratio. While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm ( 0.65 in) gauge from real life prototype 1,435 mm ( 4 ft 81⁄2 in) standard gauge standard gauge. Conversely, modeling standard gauge in Lego trains would yield a scaling of (37.5:1435 =) 1:38.3.
Modified choke or cylinder bore was furnished at no extra charge on special order only. The M37 was chambered in the following gauges and shells respectively: 12, 16, 20, 28, and 410 using 2 + 3 ⁄ 4-inch, 2 + 7 ⁄ 8-inch, 3-inch shells. The M37 unit weight was between 5 + 3 ⁄ 4 and 6 lbs; the fluctuation was dependent on the chambered gauge.
X. 0. In particle physics, the X and Y bosons (sometimes collectively called " X bosons " [1] : 437 ) are hypothetical elementary particles analogous to the W and Z bosons, but corresponding to a unified force predicted by the Georgi–Glashow model, a grand unified theory (GUT). Since the X and Y boson mediate the grand unified force, they ...
Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use. The steel groups are indicated below:
Ten and a quarter inch gauge (or X scale) (10 + 1 ⁄ 4 in / 260 mm) is a large modelling scale, generally only used for ridable miniature railways. Model railways at this scale normally confine the scale modelling aspects to the reproduction of the locomotive and with steam locomotives the accompanying tender .
