In regard to new or newly equipped lines or newly introduced rolling stock a Member State may specify conditions under which a recognised training centre may organise practical training in derogation to Article 4(2)(c).

The use of this derogation shall be strictly limited to the case in which no trainer holding a certificate already covering the new or newly equipped line or the new rolling stock is yet available.

The trainer shall fulfil all other requirements of Article 4(2)(c) in regard to the licence and to the certificate as provided in Articles 14 and 15 of Directive 2007/59/EC, and to the required period of professional practice.
