According to an article on railturkey.org, five GE PowerHaul locomotives were delivered to TCDD last year. For 2015, the delivery of a further 10 locomotives is planned.

No specific service numbers are mentioned, but according to our information, the five units delivered last year joined the TCDD fleet in March and are DE36001-DE36005. This means that this year DE36006-DE36015 will be added to the TCDD fleet, which leaves DE36016-DE36020 for (most likely) 2016.
