<P0-S0> the harmelen train disaster was the worst railway accident in the history of the netherlands on 8 january 1962. harmelen, in the central netherlands, is the location of a railway junction where a branch to amsterdam leaves the rotterdam to utrecht line. <P0-S1> it is common at high-speed junctions to avoid the use of diamond crossings wherever possible — instead a ladder crossing is employed where trains destined for the branch line cross over to the track normally employed for trains travelling in the opposite direction for a short distance before taking the branch line. <SEP> <P1-S0> guilty of treason is a 1950 american drama film directed by felix e. feist and starring charles bickford, bonita granville and paul kelly. <P1-S1> also known by the alternative title treason, it is an anti-communist and anti-soviet film about the story of józsef mindszenty, a roman catholic cardinal from hungary. <P1-S2> mindszenty spoke out against the nazi occupation of his country during world war ii, as well as the later communist regime. <P1-S3> because of his opposition to the soviet regime, mindszenty was arrested and tortured. <P1-S4> after his release, he took refuge in the us embassy in budapest for many years, maintaining his support for the hungarians who wanted an end to the russian occupation. <SEP> <P2-S0> In 1968, Tito offered Czechoslovak leader Alexander Dubček to fly to Prague on three hours notice if Dubček needed help in facing down the Soviets. <P2-S1> In April 1969, Tito removed generals Ivan Gošnjak and Rade Hamović in the aftermath of the invasion of Czechoslovakia due to the unpreparedness of the Yugoslav army to respond to a similar invasion of Yugoslavia. <SEP> <P3-S0> Because of its neutrality, Yugoslavia would often be rare among Communist countries to have diplomatic relations with right-wing, anti-Communist governments. <P3-S1> For example, Yugoslavia was the only communist country allowed to have an embassy in Alfredo Stroessner's Paraguay. <P3-S2> One notable exception to Yugoslavia's neutral stance toward anti-communist countries was Chile under Pinochet; Yugoslavia was one of many countries which severed diplomatic relations with Chile after Salvador Allende was overthrown. <P3-S3> Yugoslavia also provided military aid and arms supplies to staunchly anti-Communist regimes such as that of Guatemala under Kjell Eugenio Laugerud García. <SEP> <P4-S0> Currently, the army is divided into the Regular Army, the Army Reserve, and the Army National Guard. <P4-S1> The army is also divided into major branches such as Air Defense Artillery, Infantry, Aviation, Signal Corps, Corps of Engineers, and Armor. <P4-S2> Before 1903 members of the National Guard were considered state soldiers unless federalized (i.e., activated) by the President. <P4-S3> Since the Militia Act of 1903 all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state or territory and, when activated, as a reserve of the U.S. Army under the authority of the President. <SEP> <P5-S0> Prague underground was an underground culture developed in Prague, Czechoslovakia in the late 1960s and 1970s during the Normalization period. <P5-S1> The movement was characterized by resistance against conformity, conventions, and consumerism. <P5-S2> Because of its non-conformity, it had serious problems with the communist regime which considered it as a political opposition.
