I have been referring to the following web site from the UK for several years that shows the variety of MTH standard gauge offerings locomotives and sets from 2000 to 2017. I am amazed at what has been produced. Clearly the leader in Standard Gauge varieties is MTH surpassing Lionel, Flyer and Ives.
