when do trains have to blow their horns
Train horn On April 27, 2005, the Federal Railroad Administration (FRA), which enforces rail safety regulations, published the final rule on the use of locomotive horns at highway-rail grade crossings.[4][5] Effective June 24, 2005, the rule requires that locomotive horns be sounded at all public grade crossings at least 15 seconds, but not more than 20 seconds before entering a crossing.[6] This rule applies when the train speed is below 45 mph (70 km/h). At 45 mph or above, trains are still required to sound their horn at the designated location (usually denoted with a whistle post).
Running of the Bulls The length of the run is 875 meters (957 yards). It goes through four streets of the old part of the city (Santo Domingo, Ayuntamiento, Mercaderes and Estafeta) via the Town Hall Square and the short section "Telefónica" (named for the location of the old telephone office at end of Calle Estafeta) just before entering into the bullring through its callejón (tunnel).[2] The fastest part of the route is up Santo Domingo and across the Town Hall Square, but the bulls often became separated at the entrance to Estafeta Street as they slowed down. One or more would slip going into the turn at Estafeta ("la curva"), resulting in the installation of anti-slip surfacing, and now most of the bulls negotiate the turn onto Estafeta and are often ahead of the steers. This has resulted in a quicker run. Runners are not permitted in the first 50 meters of the encierro, which is an uphill grade where the bulls are much faster.[citation needed]
