Locomotiva realizat\u0103 de Siemens avea numai 3 CP (2,2 kW) \u0219i atingea o vitez\u0103 maxim\u0103 de 7 km\/h reu\u0219ind s\u0103 transporte 18 c\u0103l\u0103tori pe o linie expozi\u021bional\u0103, av\u00e2nd un traseu circular de 300 m lungime. Locomotiva era alimentat\u0103 cu curent continuu de 150 V prin intermediul uneia din \u0219ine \u0219i a unei a treia \u0219in\u0103 central\u0103. \u00cen patru luni de func\u021bionare, acest trenule\u021b electric (ecartamentul era doar de 49 cm) a transportat peste 86.000 de vizitatori.<\/p>\n

Pe 31 mai 1931 se n\u0103\u0219tea\u00a0John Robert Schrieffer, fizician american, laureat, \u00eempreun\u0103 cu John Bardeen \u0219i Leon Neil Cooper, \u00een 1972, al Premiului Nobel pentru Fizic\u0103 pentru dezvoltarea teoriei BCS, prima teorie microscopic\u0103 de succes a superconductivit\u0103\u021bii.<\/p>\n
