yard operations

[wickman]

Hiya Folks
I'm trying to figure out yard operations here that will work the best for the
amount of room I have on the layout
I made a couple yard versions up and I'm wandering which would be the more
effective.
When a train comes off the main line pulling the train into the siding which is
attached to a stub yard would the engine disconnect from the cars run back
around to the rear of the train cars and push the cars into the stub end Or
would the train pull in disconnecting the engine then a switcher come into play
breaking the train apart on the siding and sort the cars as there put into the
stub end yard?
Here's the 2 versions I did both work although the second version works better
if the engine is going to drop the train cars as one group then a switcher come
and starting from the back take a few cars at a time and run them down to the
stub yard. The first version can't do it that way as there's not enuff room for
it to back up with the cars.
This is Version 1

This is version 2

A classification yard normally has a switcher assigned. Of course, real yards aren't usually this small...

The short answer is "yes".

The prototype does it both ways, depending on a whole bunch of factors.

The CPR yard in Orangeville, ON was quite large. It had a 5 stall roundhouse, and pretty decent steam engine service. MOW equipment for the division was stored here too. Despite all this, there was no dedicated switcher. All road engines had to do their own work.

Thanks for input which version would work better though as one is only good for running around to the back of the train version2 and version 2 is more for pushing the entire load of cars into the yard for latter switching and sorting ?

These would be senario 1 where the train comes in to the a/d disconnects runs around to the back of the train grabs a few cars at a time then runs them down to the stub yard








This would be senario plan yard 2 where the train can come in from either direction disconnects from train runs around and pushes the cars in to the stub yard for later sorting





Now whether the main line loco does the switching or moving of cars isn't the question its which scenario would work better for a 10 car train ?
