A multi-system GRIFFIN is the first trac­tion vehicle from the family of four-axle elec­tric and die­sel loco­mo­ti­ves, offe­ring their users the whole range of trans­port and tech­ni­cal possibilities.

The loco­mo­tive is inten­ded to pull fre­ight tra­ins of a weight of up to 3200t with the speed of up to 140 km/h and pas­sen­ger tra­ins with the speed of up to 200 km/h.

Tech­ni­cal para­me­ters of GRIFFIN are tailo­red to users’ indi­vi­dual requ­ire­ments. It is cha­rac­te­ri­sed by the highest safety level, full ame­ni­ties, high com­fort of the driver’s work, and the intel­li­gent sys­tem of energy mana­ge­ment. Thanks to its modu­lar struc­ture, GRIFFIN is offe­red in seve­ral ver­sions based on maxi­mum num­ber of com­mon com­po­nents.

Some of the basic featu­res of GRIFFIN inc­lude motors powe­red by IGTB-based trac­tion inver­ters, the on-board dia­gno­stics sys­tem with com­pre­hen­sive visual infor­ma­tion and a data recor­ding module or the camera sys­tem. The loco is adap­ted for ERTMS and GSM-R installation.

Meeting the EU and UIC requ­ire­ments, the loco­mo­tive has not lost ano­ther of its major advan­ta­ges, namely its com­pe­ti­tive price.

GRIFFIN  is an ideal response to varied needs of the Euro­pean mar­ket the­re­fore it had its offi­cial unve­iling during the INNOTRANS 2012 Inter­na­tio­nal Trade Fair in Berlin.

The company’s pro­duc­tion sys­tem and high stan­dards con­fir­med by such cer­ti­fi­ca­tes as the Inter­na­tio­nal Rail­way Indu­stry Stan­dard IRIS (manu­fac­tu­ring, design, deve­lop­ment and main­te­nance acti­vity for the loco­mo­ti­ves) and the PN-EN ISO 9001:2009 guaran­tee the highest Euro­pean quality of GRIFFIN locomotive.
