E.444.001 "Tartaruga" Prototipo

"Tartaruga" Prototipo CENNI STORICI

<p> Il primo prototipo, la <b>E.444.001</b> venne consegnata nel luglio del <b>1967</b> e fu subito oggetto di prove e sperimentazioni. <br> La prima corsa prova fu effettuata sulla Direttissima Roma-Napoli alla trazione di 6 carrozze UIC-X e un bagagliaio alla media di 143 km/h, un fatto notevole, allora, dato che le 646 erano autorizzate alla velocità massima di 140 km/h.<br> Gli altri 3 prototipi vennero messi su rotaia tra il <b>1967 e il 1968</b>. <br> Erano macchine piuttosto potenti per l'epoca, oltre 3 MW, ma non abbastanza per l'utilizzo su linee rapide: inoltre i loro carrelli erano limitati a soli 180 km/h. <br> La cassa delle E.444 primo modello era squadrata, e risentiva fortemente delle linee delle motrici di vecchia generazione ignorando le esperienze di aerodinamica portate avanti per gli elettrotreni con il progetto ETR 300.<br> Nonostante tutto furono estremamente innovativi per l'epoca, e il prototipo 001 venne inviato a Copenaghen ad una mostra ferroviaria suscitando ammirazione.<br> <b>l'8 novembre 1967</b> ci fu il <b>viaggio inaugurale</b>: la E 444.001, con alla guida i macchinisti Arrighi e Pini, partì dal binario 1 della stazione di Roma Termini alle 9:00 alla testa del treno TV33069 diretto a Napoli (linea Direttissima via Formia); la macchina compì il suo viaggio in soli 88 minuti toccando i <b>207 km/h</b> (allora considerata alta velocità) tra le località di Campoleone e Latina. </p>

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the lorem ipsum generators on the internet tend to repeat predefined chunks as necessary, making this the first true generator on the internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour.
