G<\/span>lob\u00adal\u00adiza\u00adtion in recent decades has led to greater pros\u00adper\u00adi\u00adty and inno\u00adva\u00adtions. Yet, it has also cre\u00adat\u00aded new prob\u00adlems: World\u00adwide, the trans\u00adport sec\u00adtor alone is respon\u00adsi\u00adble for about a quar\u00adter of all car\u00adbon emis\u00adsions. One path to sus\u00adtain\u00adable and fit-for-the-future mobil\u00adi\u00adty is through rail trans\u00adport pow\u00adered by green elec\u00adtric\u00adi\u00adty. After all, in Ger\u00admany alone, 74 per\u00adcent of all train kilo\u00adme\u00adters are already elec\u00adtri\u00adfied.<\/p>\n

Far less is discussed\u2014at least publicly\u2014about the loco\u00admo\u00adtives, rail\u00adcars, and dri\u00adve con\u00adcepts than about the rails. The ques\u00adtion of how to con\u00advert elec\u00adtric\u00adi\u00adty into motion as effi\u00adcient\u00adly and reli\u00adably as pos\u00adsi\u00adble is just as excit\u00ading \u2014and one that trans\u00adformer man\u00adu\u00adfac\u00adtur\u00aders and devel\u00adop\u00aders have been work\u00ading on inten\u00adsive\u00adly for a long time.<\/p>\n

An elec\u00adtric dri\u00adve in a mov\u00ading object places spe\u00adcial demands on tech\u00adnol\u00ado\u00adgy. This is par\u00adtic\u00adu\u00adlar\u00adly the case for the trans\u00adform\u00aders that con\u00advert cur\u00adrent from over\u00adhead lines to dri\u00adves. In addi\u00adtion, the per\u00adfor\u00admance of the trans\u00adform\u00aders has an impact on the per\u00adfor\u00admance and safe\u00adty of the entire train. In con\u00adtrast to con\u00adven\u00adtion\u00adal trans\u00adform\u00aders, they must be opti\u00admized for use in motion as well as in var\u00adi\u00adous air and tem\u00adper\u00ada\u00adture con\u00addi\u00adtions and be par\u00adtic\u00adu\u00adlar\u00adly robust.<\/p>\n

Just like with sta\u00adt\u00adic trans\u00adform\u00aders, a fail\u00adure dur\u00ading oper\u00ada\u00adtion results in sig\u00adnif\u00adi\u00adcant costs and prob\u00adlems. If a mal\u00adfunc\u00adtion occurs in the mid\u00addle of nowhere, in the worst case it can take hours for a tech\u00adni\u00adcian to arrive on site and start repairs. And then there\u2019s the blocked track. A sin\u00adgle mal\u00adfunc\u00adtion can there\u00adfore quick\u00adly cause a cas\u00adcade of addi\u00adtion\u00adal prob\u00adlems and costs. This is true in the dense Euro\u00adpean net\u00adwork and even more so in less devel\u00adoped net\u00adworks with\u00adout par\u00adal\u00adlel branch lines.<\/p>\n

A transformer becomes small<\/h2>\n

The glob\u00adal mar\u00adket wants rail trans\u00adform\u00aders that can be used flex\u00adi\u00adbly, and com\u00adpo\u00adnents such as MR Trac\u00adtion Solu\u00adtions that can be assem\u00adbled just as flex\u00adi\u00adbly so that they are com\u00adpat\u00adi\u00adble with the wide range of dri\u00adves. When talk\u00ading about trains, many peo\u00adple often think of \u201cloco\u00admo\u00adtives with elec\u00adtric dri\u00adves inside\u201d. But it\u2019s not that sim\u00adple.<\/p>\n

The clas\u00adsic con\u00adcept with a trac\u00adtion trans\u00adformer in the locomotive\u2019s main room is the dom\u00adi\u00adnant one for freight trains. Here it is impor\u00adtant to be able to assem\u00adble trains from wag\u00adons and trac\u00adtion engines as desired. In pas\u00adsen\u00adger trans\u00adport, mod\u00adern trains now often form a unit con\u00adsist\u00ading of the dri\u00adve and wag\u00adons with the aim of mak\u00ading max\u00adi\u00admum use of the enclosed vol\u00adume. There\u00adfore, trac\u00adtion trans\u00adform\u00aders are very often locat\u00aded on the roof, espe\u00adcial\u00adly in local pub\u00adlic trans\u00adport. In con\u00adtrast, in high-speed trains, they are often placed under the wag\u00adon. There, they opti\u00admize weight dis\u00adtri\u00adb\u00adu\u00adtion at 250 or 300 kilo\u00adme\u00adters per hour.<\/p>\n

<\/p>\n

\u201cIn a pri\u00adma\u00adry sub\u00adsta\u00adtion, the size and weight of the trans\u00adformer large\u00adly don\u2019t mat\u00adter. On the rail, we say: The lighter and small\u00ader, the bet\u00adter.\u201dTul\u00adlio Man\u00adtoan, Region\u00adal Sales Advi\u00adso\u00adry<\/cite><\/p><\/blockquote>\n

For all oper\u00ada\u00adtions, how\u00adev\u00ader, every kilo\u00adgram counts, and \u201cless\u201d is par\u00adtic\u00adu\u00adlar\u00adly impor\u00adtant for mod\u00adern pas\u00adsen\u00adger train con\u00adcepts where not only speed mat\u00adters, but also accel\u00ader\u00ada\u00adtion and decel\u00ader\u00ada\u00adtion, with the mov\u00ading mass play\u00ading a huge role. The lighter the train, the less time it takes to brake into or accel\u00ader\u00adate out of a sta\u00adtion. This reduces cycle times at sta\u00adtions, trav\u00adel time from stand\u00adstill to stand\u00adstill, and of course ener\u00adgy con\u00adsump\u00adtion.<\/p>\n

The sec\u00adond fac\u00adtor after weight is space. The space avail\u00adable in a freight loco\u00admo\u00adtive is lim\u00adit\u00aded but com\u00adpared to this, what mod\u00adern com\u00admuter or high-speed trains demand of trac\u00adtion trans\u00adform\u00aders is rad\u00adi\u00adcal: \u201cThere is bare\u00adly any space on the roof or between the wheels. In addi\u00adtion, air resis\u00adtance and flow opti\u00admiza\u00adtion in tun\u00adnels are key issues here,\u201d says Tul\u00adlio Man\u00adtoan, Region\u00adal Sales Advi\u00adso\u00adry at MESCO Rein\u00adhausen. \u201cThat\u2019s why it\u2019s crit\u00adi\u00adcal for both appli\u00adca\u00adtions that the con\u00adcrete design of the trans\u00adformer mod\u00adels can be adapt\u00aded to the indi\u00advid\u00adual train mod\u00adel. This is the only way rail design\u00aders can make ide\u00adal use of the avail\u00adable space.\u201d<\/p>\n

Mobile vs. stationary<\/h2>\n

Rail trans\u00adform\u00aders also dif\u00adfer from their sta\u00adtion\u00adary rel\u00ada\u00adtives in their inner work\u00adings. Where\u00adas pow\u00ader trans\u00adform\u00aders can be sin\u00adgle-phase or three-phase, rail\u00adroad trans\u00adform\u00aders are always sin\u00adgle-phase shell or core trans\u00adform\u00aders. In con\u00adtrast to the 50 to 60 Hz of sta\u00adtion\u00adary trans\u00adform\u00aders, they also oper\u00adate at a fre\u00adquen\u00adcy of less than 25 Hz with alter\u00adnat\u00ading cur\u00adrent at an appar\u00adent pow\u00ader of about 1,000 to 2,500 kVA.<\/p>\n

Some devices may also include induc\u00adtors (reac\u00adtors) for addi\u00adtion\u00adal DC fil\u00adter\u00ading, thus com\u00adbin\u00ading all mag\u00adnet\u00adic com\u00adpo\u00adnents into a sin\u00adgle hous\u00ading. For cool\u00ading and insu\u00adla\u00adtion, they do not use min\u00ader\u00adal oils but rather ester- or sil\u00adi\u00adcone-based flu\u00adids that oper\u00adate at tem\u00adper\u00ada\u00adtures of 100 to 150 degrees Cel\u00adsius. They also often have the option of exter\u00adnal cool\u00ading. Man\u00adtoan explains. \u201cThe prac\u00adti\u00adcal rea\u00adson is that these flu\u00adids are far less flam\u00adma\u00adble and, at the same time, less coolant is need\u00aded. This also makes trac\u00adtion trans\u00adform\u00aders pio\u00adneers in the use of alter\u00adna\u00adtive insu\u00adlat\u00ading flu\u00adids.\u201d For the same rea\u00adsons, they are also increas\u00ading\u00adly replac\u00ading their fos\u00adsil pre\u00adde\u00adces\u00adsors in oth\u00ader appli\u00adca\u00adtions.<\/p>\n

What else should a trac\u00adtion trans\u00adformer be able to do? Fire, impact, and vibra\u00adtion resis\u00adtance are obvi\u00adous. But cor\u00adro\u00adsion resis\u00adtance is equal\u00adly impor\u00adtant, par\u00adtic\u00adu\u00adlar\u00adly for the mod\u00adels mount\u00aded under\u00adneath or on top of the train. And then there is the cli\u00admate itself. Since most trac\u00adtion trans\u00adform\u00aders are mount\u00aded on the out\u00adside of the loco\u00admo\u00adtive, they oper\u00adate under extreme con\u00addi\u00adtions. There\u00adfore, the trans\u00adformer hous\u00ading design is often cre\u00adat\u00aded hand in hand with train man\u00adu\u00adfac\u00adtur\u00aders to opti\u00admal\u00adly match the loco\u00admo\u00adtive and its trac\u00adtion motors to the envi\u00adron\u00adment. To meet these high and vary\u00ading require\u00adments, Rein\u00adhausen Trac\u00adtion Solu\u00adtions com\u00adpo\u00adnents are spe\u00adcial\u00adly opti\u00admized for these con\u00addi\u00adtions.<\/p>\n

The green rail<\/h2>\n

Trains are more effi\u00adcient than the equiv\u00ada\u00adlent truck or car con\u00advoys, even when pulled by diesel loco\u00admo\u00adtives. This applies to ener\u00adgy con\u00adsump\u00adtion and car\u00adbon emis\u00adsions, and also to tire wear and ground seal\u00ading. That is why shift\u00ading traf\u00adfic to the rails is cru\u00adcial in the medi\u00adum and long term to achieve cli\u00admate tar\u00adgets. But the real\u00adly big poten\u00adtial of rail trans\u00adport is the pos\u00adsi\u00adbil\u00adi\u00adty of sup\u00adply\u00ading clean dri\u00adve ener\u00adgy direct\u00adly to the dri\u00adves on long routes with\u00adout the need for a bat\u00adtery. There\u00adfore, inten\u00adsive efforts and major invest\u00adments are being made on all con\u00adti\u00adnents to improve and expand the elec\u00adtric rail net\u00adwork.<\/p>\n

The oth\u00ader side of the coin involves stan\u00addard\u00adiz\u00ading rails and rail\u00adroads across nation\u00adal bor\u00adders to build con\u00adti\u00adnent-wide, long-dis\u00adtance trans\u00adport net\u00adworks all over the world. In 2021, for exam\u00adple, the \u201cYear of Rail,\u201d this was the focus of the EU which, togeth\u00ader with the Asian mar\u00adkets, is one of the biggest investors in the rail of tomor\u00adrow. Even today, much time is lost on long-dis\u00adtance trips in Europe because loco\u00admo\u00adtives or even trains have to be changed at nation\u00adal bor\u00adders. That is now sup\u00adposed to change. For exam\u00adple, the Bren\u00adner Base Tun\u00adnel will lessen the strain on the road net\u00adwork across the Alps. \u201cThe goal is to trans\u00adport pas\u00adsen\u00adgers and goods in high-speed trains from Italy through Aus\u00adtria to Ger\u00admany start\u00ading in 2030,\u201d says Man\u00adtoan, who will ben\u00ade\u00adfit from the route him\u00adself if the Rein\u00adhausen loca\u00adtions in Italy and Ger\u00admany are brought a lit\u00adtle clos\u00ader togeth\u00ader.<\/p>\n

Over countries and continents<\/h2>\n

The most ambi\u00adtious project of this kind is the Chi\u00adnese \u201cOne Belt, One Road\u201d project, often called the \u201cnew Silk Road,\u201d in which the expan\u00adsion of inter\u00adcon\u00adti\u00adnen\u00adtal rail links plays a major role. African coun\u00adtries such as Ugan\u00adda, Kenya, and Tan\u00adza\u00adnia are work\u00ading to rebuild old dis\u00adused rail lines from the Colo\u00adnial Era to cre\u00adate a Cen\u00adtral and East African rail net\u00adwork. And a glance at the Amer\u00adi\u00adc\u00adas demon\u00adstrates that huge invest\u00adments are planned for expand\u00ading rail trans\u00adporta\u00adtion there as well. All of this shows that even though the devel\u00adop\u00adment toward cli\u00admate-com\u00adpat\u00adi\u00adble glob\u00adal mobil\u00adi\u00adty is an enor\u00admous under\u00adtak\u00ading, the sig\u00adnal lights are green. The glob\u00adal mar\u00adket for trac\u00adtion trans\u00adform\u00aders alone is expect\u00aded to increase to a val\u00adue of around 750 bil\u00adlion U.S. dol\u00adlars, which is more than four per\u00adcent growth since 2018 (Unife World Rail Mar\u00adket Study). And these expen\u00addi\u00adtures are impor\u00adtant to be able to meet the high demand to some extent. At the same time, the ongo\u00ading switch from fos\u00adsil fuels to elec\u00adtric dri\u00adves means an even high\u00ader demand for elec\u00adtric\u00adi\u00adty. This is why every\u00adone involved is join\u00ading forces to make all pow\u00ader\u00adtrain com\u00adpo\u00adnents even more eco\u00adnom\u00adi\u00adcal, effi\u00adcient, and light\u00adweight.<\/p>\n
