  2. Railway signals in Germany - Wikipedia

    en.wikipedia.org/wiki/Railway_signals_in_Germany

    Indicates that a signal at danger may be passed when wrong line working is in force. If the signal guards points/switches the speed limit is 40 km/h; otherwise, the limit is 100 km/h to the next station. As with other 'wrong line operation' signals, this is only used where wrong line operation is frequent.

    The crossover was set to diverging with a 100 km/h (62 mph) speed limit but the LZB system displayed a 180 km/h (112 mph) limit. The driver of ICE 1652 recognized the diverging signal and managed to slow down to 170 km/h (106 mph) before the crossing and the train did not derail.

    an increase of 240 dB, because the units increase by factors of 10 3 and 10 9 respectively, so: ⁡ + ⁡ = (The constants differ in the second decimal digit when the speed of light is approximated by 300 000 km/s.

    Top speed mph: mph: km/h: Maximum rate of straight line travel: higher is better Electronically limited in some cars for safety (mostly due to concerns of tire failure at high speed) A speed greater than the legal maximum/recommended speed limit can be considered as useless/unsafe.

    Speed limit 80 or 90 km/h: The speed trap uses a 1000 Hz inductor and is located at the distant signal. If train passes the speed trap with more than signaled speed + 15 km/h (i.e., 95 or 105 km/h), it will capture a 1000 Hz influence, which the train driver has to acknowledge (and brake to 55/70/85 km/h). Speed limit 100 to 140 km/h: The speed ...

  7. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    Vinyl microgroove phonograph records typically yield 55-65 dB, though the first play of the higher-fidelity outer rings can achieve a dynamic range of 70 dB. [25] German magnetic tape in 1941 was reported to have had a dynamic range of 60 dB, [26] though modern day restoration experts of such tapes note 45-50 dB as the observed dynamic range. [27]

  8. Speed limits in Germany - Wikipedia

    en.wikipedia.org/wiki/Speed_limits_in_Germany

    Speed limits are enforced with a small tolerance. In urban areas, driving merely 3 km/h (2 mph) or faster above the posted or implied speed limit is considered a punishable infraction in Germany. If the speed limit is 100 km/h (62 mph) or more, the tolerance is 3%. Other tolerances may apply for mobile speed cameras and undercover police cars.

  9. Speedometer - Wikipedia

    The indicated speed must not be more than 110 percent of the true speed plus 4 km/h (2.5 mph) at specified test speeds. For example, at 80 km/h (50 mph), the indicated speed must be no more than 92 km/h (57 mph). The standards specify both the limits on accuracy and many of the details of how it should be measured during the approvals process.
