All,

I over the last month I have picked up a bunch of Bachmann trolleys and I had a few to begin with. All the cars I have I have seen I have seen two versions of the open car, light tan and dark brown seats. And I have seen now three versions of the power brick with both the closed and open cars. The first that I saw had no soldered connections to the brick and it just screwed in. The majority of the cars I have have the brick soldered to the body for lights etc. The latest version I have purchased has sliders, and in fact the two new bricks have two different versions of sliders, smooth and with two dimples.


My question is is there a time line to their manufacturer?

Ted.

I don't have a lot of data here. I have one older open car.

It had contact fingers to connect the brick to the frame. The original brick had sliders, it was terrible. Bachmann replaced it with a different design that ran better, it did not have sliders but it did have a feature for mounting them. Both had spring contacts on top.

The brick has since been junked and replaced with an Aristo brick. MUCH BETTER

Seems the failure rate of the brick is quite often especially if using reverse units. Later RJD

Neither of the bricks actually failed. Both just ran crappy from the git-go (although the 2nd one was much better than the first) and I got tired of them.

I understand the problems with the OEM blocks. Mine are hit and miss, some really are bad, some get better with age. I kinda like the broken in blocks I have, they sound like the real thing!

I am trying to gauge the production cycle for the cars. I find it interesting that there are so many different combinations of blocks used, although I should not be surprised. There are how many different production variants of the LGB 4 wheel gondola? :)

So what I understand so far (In order of appearance)

Block with sliders, hardwired to chassis
Block w/o sliders, hardwired to chassis
Block w/o sliders, spring contacts to chassis
Block with sliders, spring contacts to chassis

George, this is akin to the different versions of the ubiquitous Bachmann 4-6-0!

All the manufacturers make changes on virtually every production run.

My trolly was purchased sometime before 1994. I don't know when they were first produced.
