Thank-you both again

Hi Have just purchased a 2-6-6-2 and have noticed that it will only travel about 250 feet or so and then it suffers from inter-mintent running e.g.
stops for 10 to 20 seconds then starts again , runs , then stops.
Am running Spectrum Controller/Transformer (16V)
Apart from that it is a fantastic Locomotive.
Any ideas as to the stop/start problem.
Thank You
Chris.
