Scratch building detailed bridge track

[Engfanuk]

Hi guys I could do with your thoughts or advice. As I live in the UK US track supplies are somewhat difficult. I chose ME code 70 and brought back supplies on a vacation in Orlando last year. Now I have decided I do want a through girder bridge on the layout so I am trying to decide what to do for bridge track. If it were inexpensive to get hold of ME code 70 bridge track in the UK I would go that route but as it isn't I'm considering scratch building.

Here's the plan. Buy a Central Valley through girder bridge. Strip code 70 rail from some flex track and apply to the bridge ties supplied with CV bridge kits. Then I need guard rail including the angle sections. As I understand it's usual to go the next code down I am unsure what rail to use. Code 55 rail is available from C&L in the UK <!-- m --><a class="postlink" href="http://www.finescale.org.uk/index.php?route=product/product&path=346&product_id=3296">http://www.finescale.org.uk/index.php?r ... ct_id=3296</a><!-- m --> but I am unsure how well that matches US rail profile or even if my skills are up to that.

I could go for the Walthers code 83 bridge track but I'm unsure how that will look on an un-ballasted track bridge transitioned to ME code 70.

Any other options or advice?

Many thanks,

Steve.
