Greetings all,

In looking for a 7039 signal this morning, I ran across one I didn't recognize at the bottom of the box my dad had given me last year. It appears older that most of my other stuff. Can anyone shed some light on this for me? What was it used for?

Thanks in advance.
Regards,
Selim

Hi Selim,

This signal stood at the top of a marshaling hump. From the 1957 US-catalogue (already with the new order-number):

Hi Markus,

Thanks for the reply. Do you or has anyone else here used this type of signal on their layout? I am not clear on how to use it in a prototypical fashion. A marshaling hump? Does this mean that all shunters would be able to see this in a yard and it applies to all traffic that can see it?

Thanks
Regards,

A marshalling hump consists of one or more tracks that have a slightly higher elevation than the rest of the yard(a hump). Behind this is a slope that descends to a yard that fans out from this hump track. Wagons are uncoupled groups according to their destinations, so you now have a whole train full of uncoupled wagons. A shunter then gets beehind the train and pushes the wagons over the hump slowly so the wagons roll down the slope one by one. in a central tower routes are set up in the yard below to divert each induvidual wagon to an allocated track depending on it's intended destination.

Your signal indicates wether the uncoupled train can go over the hump or not.

Hi,

I recommend this link with some photos of the large prototype. Please scroll down to the Hamburg-pictures:
