The COS.MO Family,

Fig 1 Famiglia COSMO

includes four locos, each produced in several versions which are flanked by some coaches. The material of this brand is very dear for the time and often shops like Mastro Geppetto in Milan,

ย keep it whole or in part only on order.
The electric locomotive called “Gottardo”, shown in the price lists as “railcar”, comes in green livery

and in red / brown livery.

Gottardo marrone
ย It is a locomotive freelance three axes, inspired Swiss, a relative of the RSM 800 Maerklin and other manufactured by Liliput / Mecanic-Wien, Buco and Kleinbahn.

There are known two versions, for CA to four rail system (Biaggi) and DC three rails. From a single item to another vary the diameter and the head of the screws and the shape of the fasteners on the heads.

There is also a pack full of track, transformer and three CIWL cars .

Confezione Gottardo

The cars of CIWL contained in set all have the same chassis and the same case, vary only the writings

The FNM 290

290 COS MO

it is a very nice car for the time, it makes very good the idea of โ€‹โ€‹the power of the real prototype, has some parts in common with the 691 (gears, cart with two axles, parts of the linkage, wheels carriers) and only it works in DC three rails.

Boldini 39
Like the 691 it has the steel frame and the superstructure cast metal. There are two versions which differ in certain details such as the diameter of the handrails and the bearing wheels, disc in the first version, and ray Rivarossi productionย  for the second version.

The tram was built for Rivarossi

fig 7 COS MO

and clearly inspired by the 5000 series of ATM, it exists in two versions, for DC and AC, and can mount a pantograph Nickel curl Rivarossi or trolley wheel.

fig 8 COS MO
It exists in blue, yellow,

TRAM (3)

green two-tone

and perhaps also in other colors.


The engine cowl brass (nickel-plated or not) is fixed to the case without the possibility of rotation and prevents the car to board tight curves.
The same material are made bogie and central casing, while the case is made of zinc alloy.
This takes driving current by the pantograph and by the two rails by mass to another. Its wheels are not isolated.
Its engine can be operated in DC or AC, but has only one induction coil, then this tractor does not have reverse gear.
We present here a specimen in two-tone green livery and fitted with pantograph …

… Bearing the number 632 immediately after the date of the previous blue car.

This other blue car …

…. instead has the distinction of being labeled COS.MO under the frame …

… And to be moved by a DC motor and, consequently, can reverse the gear with the reverse polarity.
And here are two rare images


of three COS.MO tram gathered together.
