Hi,

I'm a beginner in the train modeling business. Trying to look for locos with digital coupling build in like the roco 68825 (http://www.roco.com/products/Roco/68825.aspx)
Any help will be appreciated

I have 2 locos with digital coupling (Telex)

37650 V60
37885 Br 043

Märklin has different types of Telex couplers.

The old-style Telex couplers can be found with BR V 60, BR 86, BR 81. They work better with Relex couplers than with close couplers.

The new-style Telex couplers can be found with BR V 90 (#37903) and various steamers (BR 03 (#37953), BR 41 (#37921) , BR 44, BR 50). They work fine with close couplers (not tested with Relex couplers) and are much like the digital couplers used by Roco.

Roco makes models of BR V 100 West (your link) and BR V 100 East with those digital couplers. You can also by a pair of digital couplers with a "special" decoder from Roco (the "special" decoder is just an uncrippled ESU V3.0 decoder while other Roco locos used to have crippled ESU OEM decoders).

Yes. Telex can be triggered Open. Not all Locos have it.

The main difference between Marklin electrical Telex uncoupling device and Roco is: Roco can be attached to any loco having NEM coupling shafts whereas Märklin is a fixed un-coupler.
Digital uncoupler means the voltage has been set for digital operation and with ESU lokpilot or sound decoders you can also set the time for the un-coupling device to be activated by a pulse action timer.

Roco suppose to have a re-run on these un-couplers but so far I haven't been able to order them (over a 6 month period).

I have many locos with telex such as BR03, BR41, BR43, BR44, BR50, Diesel shunter, etc.

Also welcome to the forum.

It seems the coupler used with the V 90 (#37903) can be used with any loco with NEM pockets - so it's the same principle as with Roco.
Before the insolvency, they announced a 150 (#39502) with these couplers which never came.

Märklin calls it "Telex", Roco calls it "Digital Coupler" - that are just names.

Märklin Telex also works in analog operation - if the loco is analog or has a Delta decoder.

Uncoupler tracks should work with all "normal" couplers (including Märklin, Roco universal coupler, Roco close coupler, Fleischmann, ...). This principle is used by many MRR companies, not just by Märklin.
The new power conducting couplers do not work easily, so expect trouble with them; you can use normal couplers at the end of the train so you can still uncouple the loco from the train.
Don't mix close couplers with bow and hook couplers, this can lead to problems.
Fixed coupling bar and special power conducting couplers won't work.

Roco universal couplers normally close more easy than Märklin couplers, so if you want to use uncoupler tracks give those Roco couplers a try (unless you live in Italy).

take into consideration: except Märklin costs twice as much.

I paid Euro 90 for one Roco V 100 with digital couplers.
The other Roco V 100 with digital couplers cost me Euro 185 together with eight four-axled freight cars.

So yes: the V 60 from Märklin (with those old-fashioned Telex couplers) will normally cost twice as much as my Roco locos ...

Thanks Joe.

John,

The Telex coupler from Märklin #37921 is listed as Euro 25 (spare part price) and it's available.
The Telex coupler from Märklin #37903 is listed as Euro 15 (spare part price), but is not available.

A pair of Roco uncouplers plus ESU V3.0 decoder is available for Euro 60 (street price; their site is down so I can't check the RRP).

Krois couplers are listed as Euro 17.

So prices appear to be similar IMHO.

But that's not the new Telex coupler used with the big steamers (BR 03, BR 41, BR 44, BR 50) or the V 90.
