Since you're asking a question, I wonder if a blog is the best medium for this. Wouldn't you be better posting to the ongoing Lion topic in the main forum?

Thanks,first time user, will get use to where I am suppose to put my comments!

I don't have a Heljan Lion , but their 47s in particular have a reputation for drawing large amounts of current and the Hornby decoder isn't rated to stand more than 0.5A on a sustained basis.

That doesn't explain a dead Bachmann decoder though

New lion arrived,Bachmann decoder fitted and every thing is good.Loco runs well and lights work as intended.

Thanks for comments to a new user.
