        Due to the reson we also cannot test all circumstances / do not know all boundary conditions:
        please let us know in case you have other experiences, that we can add these informations
        in below list - thank you

GB2-8025 Massoth 8414002
(LGB-style like LGB Duo) LGB Duo

Installation / compatiblity for following models: Since introduction of the automatic uncoupler GB2-8025 all locomotives we got since that time could be converted with an uncoupling system.
In some cases the installation / mounting is easy; in other cases of course modifications are required
Installation / mounting possible according list in opeartion manual of Massoth. Originally only available in LGB item 2190 / 2390.
Instalaltion in different locomotive(s) requires significant modification

Connection to MTS decoders Can be connected to all MTS decoders having a servo interface or using a separate function decoder with servo interface Can be connectet to all decoders with function output;
precondition: U+ power supply of the decoder can supply about 200mA (what is usually always the case)
   Additional electronic necessary in order to operat the motor in the gear box of the uncoupling

Uncoupling with "jolted" cars                 Yes                 No

Motor and uncoupling loop are not flexible mounted to each other; therefor ein case train is jolted the loop cannot move and the hook cannot uncouple
                    Yes

Motor and uncoupling loop are not felxible mounted ; therefore even if the train is "jolted" after pulling backward the hook can slide out of the loop chamfer

Uncoupling with "elongated" cars                 Yes
                Yes
                Yes

Uncoupling uphill                 Yes                 Yes;

please refer also to operation manual of Massoth automatic uncoupler
                   Yes

Uncoupling within small curves (1200 mm diameter)                 Yes                 Yes                 Yes

Freilandtauglichleit
(Wintertauglichkeit)                 Yes;

due to the reason that
- the servo can be mounted inside
- if the servo is mounted inside
the loco the electronic parts can be protected


the uncoupling os only available since mid of september 2012; long time experience is not available up to now;

furthermore: please refer also to operation manual of Massoth automatic uncoupler

                Yes;

reason: motor is placed in gearbox inside loco and therefore protected;

at least the customized LGB 2062from 2002 we are running since that time never had a problem

[if rolling resistances is increased]

                No

[the hook does not slide out on the chamfer, becasue car is to smooth-running and force is not enough to let hook slide out

Summary:

All tested uncouplers are suitable within its boudary conditions using

- assymetric hook and loop from LGB (what might be mostly the case)

- even tracks
Installation of the systms is depending on the locomotive more or less difficult
Using symmetric hook and loop with LGB style uncoupling is working not in all cases (mainly non LGB cars)
Remark: in all cases a correct installation of the system is a necessary precondition

Test conditions:

Test time:
    Massoth uncoupling system since 08. September 2012 on our layout
    LGB Duo since 2002 on our layout
    GB2-8025 since 2001 on our layout;

Test GB2-8025:
    LGB loco self build based on LGB 2051 basis
    Uncoupling mounted both ends
    Decoder: Zimo MX695KN
    Installation with normal servo in front
    Installation with powerful servo in rear
    Above tests done with front as well as rear uncoupling GB2-8025 system

Test Massoth 8414002
    LGB locomotive 23620 with installed uncoupler Massoth 8414002 in front and rear
    Decoder: Massoth XL
    Above tests done with front as well as rear uncoupling

Test LGB MZS Duo
    LGB locomotive 2062 with installed LGB MZS Duo uncoupling in front and rear
    Decoder: Zimo MX64H
    Above tests done with front as well as rear uncoupling

    PikoG high sided gondola 2-axle with original Piko hook and loop
    Aristocraft Box Car 4-axle with original Aristocraft hook and loop
....Train Line HSB passenger car with original Train Line hook and loop

Boundary conditions:
    Test with
        - ESU Ecos central station
        - PikoG central station with remote Massoth Navigator plus
        - Zimo central station MX31ZL / MX1HS with MX31Fu
        - Massotth central station Dimax 12A
        - Ulhlenbrock central station Intellibox II
    Test of all locos with symmetric hook and loop on our test layout
    Test with slope of 4%
    track voltage approximately 22V

Remark:
        Due to the reson we also cannot test all circumstances / do not know all boundary conditions:
