Stab in the dark

Dear Patrick,

Total stab in the dark, but based on:
- Assuming HO scale
- Looking like a Free-mo style module
- Typical F<> B depth of wheeled toolboxes
- Estimation of turnout lengths VS linear clear track at either end

I'd be guessing 6' x 2'..

Using PECO Code 83 #8s,
(which is hinted-at by the angle of the front spur away from the main,
and how-far it projects towards the front-edge of the module)

that gives you:
- a Rearmost-spur capy of 2x 50' cars,
- a Front-spur (surrounded by the chainlink fence) capy of 4x 50'
- a switchback/lead capy of 2x 50' cars + a short Geep or SW loco (2' linear)

Using PECO Code 83 #6s, those spur capacities come up to 3 and 5x 50' cars respectively...
(lead/switchback capy does not change).

...however, it is screaming to me that it's part of a larger assembly,
and really isn't "fully formed" to be operated standalone, except in "enhanced diorama" mode...
(even micro-layouts of the Carl Arendt School-of-Thought have more "self contained, fully-operational" track-array headspace applied to the design than this appears to have, 
IF we assume it's meant to operate as a "single piece"...

...at the very least, to operate this "as presented", it would appear some drop-leaf linear extension-staging and possibly a sectorplate/traverser at the LH end seems needed???)

Have to ask, what's drawing you to this layout/track array?
Maybe if we know what space you have available, we may be able to guide you towaards something similar which is a bit more "fully formed"?

Happy Modelling,
Aim to Improve,

My WAG: 2' x 4'

Based on the tool cabinet (many like this are 42") and amount of overhang and the visible proportions of width to length.

It's nicely done!

Here 'ya go

Thank you

I knew I could get my answer here thank you

Thanks Professor

Appreciate your hejp

It’s reminds me of an area around me in Clackamas Oregon I like that I want to model

Commercial tool boxes like this typically have standard drawers.

That enables the manufacturer to control costs.  The bottom drawers on the box look like standard 24" wide drawers.  I just went to the garage and measured my old Snap On box that I used at work before retirement and my cheap "home owners" box from Harbor freight and found the width of the drawers of both boxes were 24".  The standard depth for a roll cab is 18" with the corner posts 18 3/4.  The distance from the edge of the drawer to the out side of the box would be about 2 3/8".  The distance between the two sets of bottom drawers would be 1"-1 1/2".  That would make the roll cab to be about 51 3/4"- 52 1/4" wide and 18" deep.  I would agree that it is a Freemo module, probably somewhere around 5' x 2'.  The length is difficult to estimate because the photo was not taken straight on and it is difficult to estimate the amount of over hang on each end of the module.

Double track modules are 26" wide.  Single track is 24" wide.
