For code 124 fb rail it might be easier for you to get some from Karlgarin Models in Chelmsford, they do very nice code 125 flat bottom rail (and O scale code 100 and 82 rails). I have both right-o-way and Karlgarin rail and they are difficult to tell apart.
Are the flat sleeper plates only for turnouts? Most sleeper plates (tie plates) are hot rolled with a 1 in 20 slope to tilt the rail.
I found a data sheet for them
http://www.karlgarin.com/rail_flatbottom_sizes.pdf and with a name like that assumed they'd be US or Aussie, turns out they're in the Chelmsford just down the road from me
Already have 6 yrds of Code 100 salvaged from a job lot of rail off Ebay, enough to get started so only Code 125 for the mains.
I only found flat tie plates on switches, the rest were ribbed.
The 2nd from the left being a narrow 4 hole plate sunken into a rotting tie, the rest being wider 8 hole plates, just had a flick through my US RAW images and found hundreds not yet processed
yet still have the feeling I should of taken more
Note also the anti creep clips, this being the lead track outside 'Rachels' of bar top..less and steak bar fame (yes it was hard to live that down to the family) where double stack trains of 6,000+ ton are started from.
Jordan, ahh, misread your comments, thought that it had all been done behind closed doors by envoy
Don't forget to leave some of your pins sticking proud, I reckon nearly 20% of the rail I saw off the mains had the tie pins sticking up
Know what you mean re P48, if starting from new then it's maybe viable, but to alter existing it becomes prohibitive. Personally I'll probably just go with O fine or what ever gauge is the norm but use finer rims and narrower check rails and crossings, I already have S7 to satisfy my 'scale' track pedant, I don't need another
I also want quite a bit of street track or at least heavily
covered so will get rid of some of a box of PECO CODE 124 BH flexitrack that way, basically anywhere where the ties are all but totally covered.
Just found Grandt line tie plates, look the part and will probably do for me for the most visual parts.
Anyways, Y'all can guess which 'interest' bubble is making a near workbench orbit
