to understand the M-track geometri

Many thanks chaps. I'll take the time to read the info you sent me, extremely useful.

Cheers,

Horacio

Horacio, I reviewed your dimensions (27" x 48") and realized you have quite a challenge. The 5100 standard radius curve track has a radius of 360mm. That works out to a diameter of 28.3" (measured from the center rail). In other words, you'll need more than 27 inches for your layout.

I've created a simple SCARM layout using your desired configuration: Horacio.pdf (267kb) downloaded 27 time(s).

Take a look at the attached file Marklin HO layouts M track.pdf (15,218kb) downloaded 36 time(s). It is in English and provides examples (dimensions in millimeters).

Horacio,

You have some options with that table.

Try using a piece of cellulose fiber sound insulation board (available as Homasote or generic brands at building supply stores), Cut it to a size that supports your compact layout (it will be slightly larger than your table).

Mount M track to the board with screws (Marklin 74990 or equivalent) and set it on the table with a bit of overhang. That will provide a lightweight, "permanent" layout that has the added bonus of being set aside in a closet when not in use. It will also be much quieter than setting the metal M track directly on a wood table.

There are plenty of reliable sources for M track, and manual turnouts are relatively inexpensive. PM me if you need help with that.

A question: do you have a Marklin transformer? The old blue transformers with metal housing have some challenges with brittle insulation and can pose a safety hazard.

I would definately look at getting C-track. And also downloading the SCRAM software - it is brilliant.

Horacio,

Welcome, and best wishes for your retirement here in sunny Florida!

I am going to play the other (dark? ) side, and work within your limit of the "Tischbahn" (I also work to small limits) and I realize the limiting that I am about to propose. Also, I am probably in a small sub-set upon the forum, so bear with me. I am also aware of what may be called the "boring factor" of what I am suggesting...hear me out, please...

"M-Track 5120 Industry radius" - it will fit the table, albeit close to the edge, and it allows for about 2-2½ straight sections in your 50" length. No real passing track would be possible, so you could only run 1-2 trains in the same direction, but, again I am working within this Tablebahn

Yes! I am also limiting your motive power and car length. Per your picture you would only be able to use the 2 steamers and the small diesel and the short cars. The e-loks and longer cars may work, it would be a "try it and see" - the Industry radius may cause longer equipment to derail.

This would allow for, say, 2 straights on each side which is 2 sidings worth of storage/display with probably only 2-3 straights and a buffer on each siding. I, myself, have "waffled" back and forth as to "how many sidings per side", but I kind of think 2 sidings on one side (1 RH 1 LH giving 1 parallel to the main line and 1 at an angle) and either no switch or just 1 switch for a parallel siding on the "long" straight side for a passenger station?

Just some thoughts from my own puzzlings and ruminations. I use 5120s on my layout. I also use the 5122 manual switch sets.

(p. s. - as to the sound level on plain wood vs other surfaces, I find that is part of the charm of M-Track and Tischbahn (and my pure analogue loks); it is what I remember from way back - just me)
