vehicle gauge

The second digit indicated the vehicles gauge and axle arrangement: 0, a narrow gauge railcar; 1, a standard gauge railcar; numbers 2 to 6 indicated a locomotive with that number of driving axles.

The locomotive applied modern design principles to a shunter designed for the UK market;The design is built to the standard UK vehicle gauge - as defined by drawing 'UK L-A1-1806'.

The low pulse frequency also has little impact on measurement accuracy, as these digital devices can be programmed by wheel size, or additionally by wheel or tire circumference in order to make distance measurements more accurate and precise than a typical motor vehicle gauge.
