I have one of these on my layout for the grandkids. It's a Hornby

I have a lot of trouble getting it to start.

It's on NCE Procab DCC and I have tried changing the decoder to a TCS but it's no better.

The wheels and contacts on the sides of the wheels are clean.

If I give the loco a little push, it takes off nicely.

Anyone know if the motors on these locos are suspect for reliability and if there is a way of overcoming the starting problem.

(Apologies if this blog is improper but it's the first time I've used the system)
