Can one of you well read folks please direct me to the part number for the crew step at the front right corner of SBB Re4/4 ll M.34345. This is the year 2000 limited edition model in experimental Turquoise/White colour scheme for SBB Cargo. My research so far has only found one exploded drawing for all of the Re4/4 ll models - they do not show this part - many thanks in advance.

Hi Paul - thanks for your reply, however this is the same drawing from the series that I referred to in my initial message. The part I am looking for fits UNDER the "Puffer" 489680 on the front of the "Aubau Lok" 224874. I have a hi res photo of the part - but do not know how to attach it to this thread. The Trittstufe is the same colour as the dark grey band at the base of the Lok body.

Thanks for the observations Paul - the Trittestufe is a 'detachable' part which plugs into the front end of the Lok body under the Puffer by means of two moulded pins. This is the first experience I have encountered where a removeable fitted part is not described in an official Maerklin document - some wiz at Goeppingen has gone to a lot of trouble in omitting this.

Do any of our other friends out there have an Re4/4 II of any colour that does or does not have this part - am I lucky or otherwise to have the only Re4/4 II (M34345) model with this part fitted?

Graham,

It appears that selected versions of the Marklin Ae 6/6 (six axles) have these extra steps fitted also.
Please see the red Ae 6/6 as contained in startpacking 29463,it also has these steps under the buffers.
The partcode for a set of buffers and one step is E176160.
I am not sure whether it would fit to your RE 4/4,be careful there.

Marklin have always been very good in following real life alterations to locomotives,as such each model came out in various versions over time.
Not mentioning extra parts on exploded view drawings is a serious omission.

Cheers,
Paul

Here the Ae 6/6 as contained in set 29463,the extra steps can be clearly seen under the righthandside buffer:

Hi Paul - part number set 176160 looks like the way to go - even with all the extra 'puffer' bits, many thanks again for your input

The part in question is known as the UIC Steps or UIC Treppen. It was added to SBB Loks of the classes Re 4/4II, Re 6/6 and Ae 6/6 in the 1990s to facilitate access to the new UIC connection which was built into the loks between the front windows under the top headlight. The new connection was not accessible from track level, so it was decided to modify the loks with these steps and the diagonal railing so that the crew could access this connection when needed.

Here is a list of Swiss models with this feature:

The part is listed as part of the kit including buffers for some models (as mentioned above).

I may have missed one or two
