SZENTES3 M. BOLÂNU4 C. SIMA5 D. MITU6 G. DUMITRU7 Abstract: In Europe there are countries where both freight and passenger transport are affected by different gauges. Need circulation of rolling stock gauge has resulted in looking for solutions to improve various diversified systems in operation. There are two possible solutions, namely the exchange of axles (rolling element that steering bogies) or adapt them to the new gauge on the fly (during the journey without stopping the train), for rolling stock operating on different systems to track or endowment both rolling stock and infrastructure, with an automatic gauge change. Key words: variable gauge, unconventional axles, suspensions, traffic safety. 1. Introduction These trains passed through changing track tens of thousands of times. They have The first trains offering regular been used since 1969 for international passenger transport services equipped with traffic and since 1992 also for domestic automatic gauge change system while rail services using high-speed lines driving axles are TALGO trains. First, in partially. 1969, III RD type TALGO trains (with The passenger carriages type articulated "variable gauge") and subsequently trains TALGO RD are autonomous and different in various other versions of therefore can be towed by any type of TALGO trains, equipped with a tilting box locomotive as ancillary services are technology vehicles (circulation at high supplied (insured) generating units located speeds). at the ends of the train (the second The inclination train system is already locomotive at trains traction or “end” the fifth generation, 1981.

Furthermore, Gauge Changing The frequency of use of transport Bogie - EV 90, is a gauge changeover of services increased immediately from two the bogies and in Bulgaria, The Bulgarian passengers on a wagon, until the supply of Automatic Gauge Changeover System - small vehicles daily service to Barcelona BAGCS, it is also an automatic gauge and Valencia to Montpellier in change system.

Rafila / DB AG - began with variable gauge Talgo trains in Deutsche Bahn / public limited company 1969, and to date, more than 260,000 trains (SA), is similar to the German system. and 325 million passengers used the trains. There is a generous variety of alternative In 2000, the second Spanish variable gauge names for this acronym. Some of these system developed by CAF was introduced refer to wheelsets adjustable depending on in commercial operation. the gauge (GAW - Gauge Adjustable Japan has the same internal matter Wheelsets variable gauge wheelsets). between the narrow gauge (1067 mm) and Another explanation close relates to a track "Shinkansen" (1435 mm), and switching system / automatic change of Switzerland also has two distinct types of track gauge axle (ATGCS / TGC - gauge to its network of railways (1000 mm Automatic Track Gauge Changeover / 1435 mm).

Passenger a class of trains equipped with technology carriages of the current generation began for tilting boxes and variable gauge circulating since the summer of 2000 wheelset. Three of these trains were built between Madrid and Barcelona on to provide the transport of passengers on conventional line. These trains are the route Madrid - Paris from May 1981 equipped with static frequency converters until May 1991, when this type of trains arranged in two vehicles by the end of the was replaced by the new class of trains train set, which are supplied with TALGO - the sixth generation. electricity from 3000 V the engine for this The sleeping carriages fifth generation of purpose.
