New layout, advice

[PlumbersMate]

I am about to start the build but have some concerns about the track design.

I have attached the design. I realise it is a chase-the-tail type which is not everyone's preference but I would like that as my son will be using it as well.

I wanted a large goods yard as well.

I have kept all curves to minimum R2 as I have locos with this restriction. Most of the points are Peco medium size SL-E95 & SL-E96.

My concern is that the track to edge of the board is only 5cm. So locos may fall off the edge if too fast. I can make it smaller left and right but to bring the edge track inwards on the top and bottom means I have no room to insert the points on left and right.

Can anyone one suggest an improvement? While keeping to R2 curves?

Your ideas would be appreciated.

Perspex edging screwed to board edges.

What Brian suggested.

I think the perspex idea is good. I had thought of using a board along the 'danger ' side but perspex sounds good.
It would also stop little fingers creeping on while them watch the action.
I had already thought of limiting speed via CV, will do.
