What are the ins and outs of plastic rail?

[yellow_cad]

I plan to run live steam and would like to use 45 mm plastic track. What makes of plastic track are available? Do various brands of plastic track interchange? I have seen talk of painting plastic track. What is the best type of paint to use. How is expansion of plastic track best managed? Thanks for any thoughts on plastic track. Jim

Jim,
Just to clarify, by "plastic track" I assume you mean metal ( brass, N/s, etc) rail on plastic sleepers?
I'll let others answer fully although I'm not aware that plastic sleepers are a significant problem with live steam.
In answer to your question on compatibility between manufacturers, the question of the 'code' or dimensions of the rail cross section can be an issue, although not insurmountable, and of course trying to convert between bullhead and flat bottom rail also requires some care in alignment, but again it isn't impossible.

I am asking about track that is 100% plastic (ties and rails).

There are a number of companies that make plastic track, Bachmann and some sold by ECR, however they are not compatible with each other. As for running live steam, depends on the heat from your loco!!!

Heat (gas locos should be fine but coal or meths fired will melt the track), weight and metal wheels are going to be an issue running live steamers on poorly made plastic track that is intended for toy train sets.

Electric locos should be fine using plastic track though.

From personal experience I've had no issues running internally gas fired live steam on plastic track. I'd be a bit wary with methylated spirit firing should there be a flare up, and coal fired boilers have the ash pan down close to track level. I've a couple of circles of 45mm stuff out of Christmas tree sets and an oval of 32mm Faller PlayTrain track that can I use when visiting somewhere. I'm planning a little layout using the Faller Playtrain stuff - on that note, does anyone have any PlayTrain points they'd consider getting rid of?

My ELR Hunslet running on the Faller track below. The Edrig ran just before this, and the Hunslet then ran continuously for almost an hour with no damage to the track.

An oval of plastic track used on a table indoors is not the same as installing it outside where it will be impacted by terrain and changes in temperature (the question asking how is expansion managed by the OP led me to believe he was asking for how to use plastic track outside).

I don't think plastic points are going to be durable longer term as the weight of live steam locos will wear the point frogs and blades.

I came across this chaps YouTube channel the other day while hunting for suitable scale ballast for garden railway use. He seems to have a fairly extensive railway using 45mm plastic track and has a few how to videos on various aspects of using plastic track (including one on painting it). Perhaps worth dropping him a message via his YouTube channel to see how he gets on with the issues you mention.

I am talking about running outside. Yearly temperatures vary from an occasional 105 F in the summer to an equally occasional lightly below freezing in the winter. I do plan a well packed 1/4 inch crushed gravel bed.
If the switches are the weak point, is it possible to integrate metal railed switches with plastic rail track?

My main concern with using plastic track outside would be UV. The track sold by ECR says it's suitable for outdoor use (and live steam) but doesn't mention if it's UV resistant.

I understand that some people paint the plastic track to protect against UV.

Why do you want to use plastic track?

[yellow_cad]

My thought is to use plastic track several reasons. First is cost, second is the fact that I will be placing my layout under some very messy trees (for shade and other reasons) and believe the plastic would do better in this environment, and third I thought that the natural lubrication properties of plastic would be beneficial since I do not need to conduct electricity through the rails.

Plastic track is not really much cheaper than metal, especially if you look at ebay. Sap and bird mess will ruin paint on cars, and I would think would penetrate plastic. Plastic wheel cause drag on metal rails, metal on metal being much smoother, so again I feel your reasoning may be flawed.
Obviously these are just my thoughts, and somebody could easily shoot me down.

For me it all depends on budget. Like other members have said though, metal is by far cheaper in the long run, although I would try and buy a small amount first if that's the way you are wanting to go and see how well it stands up to everyday wear and tear. By a small amount I mean just a few pieces if that's possible. Then see if it is still want you want to use. Bear in mind though that there are quite a lot of people who use coal and meths fired locos and it would frighten the life out of me if it was my track going up in flames and even more importantly, if my loco was to get fire damaged because of it.

Good points. Thanks.
