The Bo-Bo-Bo configuration is often used to lower axle weight while keeping lateral forces low compared to a locomotive with two three-axle bogies, thus allowing the locomotive to use lightly laid track, in particular narrow-gauge railways.

Designed to meet most First World, Second World and Third World countries, the G22 Series were now equipped with a naturally aspirated EMD 645 Series engine as well as four axle Flexicoil Type-B trucks which carry a low per-axle weight.

The 141Rs so prevalent on the SNCF network, saw no service on the Haut-Bugey line as their axle weight was too heavy for the rails, although they did exceptionally run up to Nantua on trains unloading rubble from the Cret d'Eau tunnel.

This electrification of the railway was carried out with a 15 kV, 16.7 Hertz system, allowing heavy trains to be pulled over the route once the tracks and supporting structures, including the Trisanna bridge in 1964, had been upgraded for the increased axle weights.
35.
Due to their size and weight, the class was restricted to the London-Taunton-Plymouth ( via both Bicester ) main lines, and even then, only after bridge strengthening had taken place, due to the engines'large boilers giving them a high axle weight of.

Unsurprisingly, the heavier vehicles reduced the serviceability in a much shorter time than light vehicles, and the oft-quoted figure, called the Generalized Fourth Power Law, that damage caused by vehicles is'related to the 4th power of their axle weight,'is derived from this.
37.
Experience with the high-speed Class 55 " Deltic " locomotives had shown that a low axle weight was essential to avoid damage to the track at sustained high speed, and that high-speed engines were the only way to provide a good enough power / weight ratio for diesels.

On 13 June 2005, Kaitaia Airport received an injection of $ 333, 850 to upgrade its runway facilities so that it can accommodate larger aircraft . The Far North District Council approved loan funding for Kaitaia Airport's project that allows it to accommodate aircraft with a PCN in mainwheel axle weight.

As a result of the Salter Report on road funding, an'axle weight tax'was introduced in 1933 in order to charge commercial motor vehicles more for the costs of maintaining the road system and to do away with the perception that the free use of roads was subsidising the competitors of rail freight.
