[1] [2] [3] Many regulatory signs are based on European signs, i.e. the Vienna Convention on Road Signs and Signals, while many warning signs are based on U.S. and Canadian signs, i.e. on MUTCD. Colombia uses the metric system of measurement and drives on the right.
The Colombian railway network has a total length of 3,304 kilometres (2,053 mi). There are 150 kilometres (93 mi) of 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge connecting Cerrejón coal mines, Tren del Cerrejón, to the maritime port of Puerto Bolivar at Bahia Portete, and 3,154 kilometres (1,960 mi) of 3 ft (914 mm) narrow gauge of which 2,611 kilometres (1,622 mi) are in use.

Colombia has 3,034 kilometers (1,885 mi) of rail lines, 150 kilometers (93 mi) of which are 1,435 mm (4 ft 8 + 1 ⁄ 2 in) gauge and 3,154 kilometers (1,960 mi) of which are 914 mm (3 ft) gauge. However, only 2,611 kilometers (1,622 mi) of lines are still in use. Rail transport in Colombia remains underdeveloped.
The ID-1 format specifies a size of 85.60 by 53.98 millimetres (3 + 3 ⁄ 8 in × 2 + 1 ⁄ 8 in) and rounded corners with a radius of 2.88–3.48 mm (about 1 ⁄ 8 in). This format is also referred to as CR-80 and, for travel documents, TD1. It is commonly used for payment cards (ATM cards, credit cards, debit cards, etc.).
Lego trains use a fixed nominal gauge of 37.5 mm (1 + 15 ⁄ 32 in), based on 5-stud track centerlines gauge. [5] [6] [7] 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 8 + 1 ⁄ 2 in) standard gauge ...

The terminal was equipped with airline service counters, restaurants, shops, a small hotel and even a nondenominational prayer chapel for nervous passengers. Although some critics initially claimed it was unnecessarily large and expensive for the city's needs at the time, air operations and passenger numbers quickly grew, justifying the size ...
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.
