The Competition Commission has published its draft undertakings to remedy an adverse effect on competition identified during its investigation into the leasing market for passenger train rolling stock. The particular anti-competitive effect arose from the Codes of Practice applied by rolling stock companies, which included non-discrimination requirements that limited the incentives on train operators to negotiate with the rolling stock companies when entering into train leases. The Competition Commission concluded that the removal of the non-discrimination provisions would provide greater incentives for train operators to negotiate, which might increase rivalry between rolling stock companies. A number of rolling stock companies have now agreed the terms of draft undertakings to remove the offending provisions. Interested parties are invited to comment on the draft undertakings by 24 June 2009.
