The single-system DRAGON is the first trac­tion vehicle of the six axle loco­mo­ti­ves family, specially tailo­red for the Polish mar­ket. Dra­gon is a power­ful, safe, attractively-priced and eco­no­mi­cal loco­mo­tive, fully-equipped and cha­rac­te­ri­sed by highly relia­ble operation.

DRAGON’s main advan­tage is a very high trac­tive force of the value of 374 kN which, in con­nec­tion with the loco­mo­tive weight of 119 t, a modern anti-skid sys­tem and an indi­vi­dual drive per each axle, allows it to drive fre­ight tra­ins of the weight up to 4500t.  The axle load below 20t com­bi­ned with a spe­cially desi­gned suspen­sion result in the fact that DRAGON is per­fec­tly adap­ted to dif­fi­cult ope­ra­ting con­di­tions and pro­ves to work effec­ti­vely on Polish rail­way tracks.

The loco’s drive is made up of asyn­chro­nous trac­tion motors dri­ven by IGTB-based trac­tion inver­ters. The loco­mo­tive has a modu­lar con­struc­tion which allows for tailo­ring tech­ni­cal para­me­ters to indi­vi­dual clients’ needs e.g., incre­asing the maxi­mum trac­tive effort to 450 kN (MAX LOAD option),  adap­ting the loco­mo­tive to 25kV Ac vol­tage or instal­ling an addi­tio­nal Die­sel  engine (DUAL POWER  option).

Loco­mo­tive design ensu­res driver’s safety and enhan­ced wor­king con­di­tions by pro­vi­ding ergo­no­mi­cal cab and con­trol panel lay­out, a double func­tion air con­di­tio­ning sys­tem, as well as a sys­tem of came­ras, a safety cage and an anti-climbing struc­ture pro­tec­ting train ope­ra­tors in the case of a collision.

Dra­gon is equ­ip­ped with a micro-processor sys­tem of con­trol, allo­wing to adapt the loco’s ope­ra­ting mode to chan­ging con­di­tions, an on-board dia­gno­stics sys­tem with full visual infor­ma­tion and a data regi­stra­tion module which faci­li­ta­tes loca­ting or pre­dic­ting possi­ble dama­ges as well as with an anti-skid system.

The imple­men­ted pro­duc­tion sys­tem and the high quality stan­dards of Newag Gli­wice S.A. (for­mer ZNLE), con­fir­med by such cer­ti­fi­ca­tes as e.g., Inter­na­tio­nal Rail­way Indu­stry Stan­dard IRIS (manu­fac­tu­ring, design, deve­lop­ment and main­te­nance acti­vity for the loco­mo­ti­ves) and PN-EN ISO 9001:2009 guaran­tee the highest Euro­pean quality of DRAGON locomotive.
