I strongly recommend that you make contact with Remco Vegting - exclusivemodels.nl - he has a lot of experience with live steam, and is the owner of the definitive love-steam store in the Netherlands. There are a few groups of live-steamers in The Netherlands, at least one of which has a large portable track. There is also a very comprehensive live-steam group in the family park in Appeldorn - Remco is a member there.
Believe it or not, running a live steamer is not as much fun doing it as a one-man band as you might think - much of the enjoyment comes from the interaction with other like-minded people, most of whom, happily, are very friendly. Also, I strongly recommend that you join the Association of 16mm Modellers - they are THE main international contact group. We have a FB page, as well as the very best 1/4-ly magazine you'll ever find - and the joining pack includes the intro book to 16mm live steaming that costs £15 if you buy it separately.
