I have the exploded view of the 2 Truck Shay, but not the Climax or 4-4-0.  Here is the link for the Shay:  http://hyaklocoworks.weebly.com/bachmann-2t-shay.html

Isn't Percy at the same coupler height as the new 1:20.3 cars?

From smallest to largest

Z - 1:220
N - 1:160
HO - 1:87
S - 1:64
O - 1:48
G - 1:32, 1:29, 1:24, 1:22.5, 1:20.3, plus a few others

It depends on what type of track you have.  If you have Bachmann track, then it is an indoor only track as it is tubular steel and will rust.  Brass, Stainless Steel, Aluminum, Nickle Silver are okay to be left outside.

That looks more like a USA Trains Reefer to me.

In regards to the "deadman switch", the runaway locomotive had one equipped.  But since the locomotive brakes had already be applied, the switch was nullified.  If the engineer had not applied the brakes before leaving the cab, the deadman switch would have activated after not receiving any command input and the train would have come to a stop.

The engineer was trying to use the dynamic brakes.  To use the dynamic brakes, a lever has to be switched to dynamics, then the throttle is used to increase or decrease the dynamic brakes.  If the lever is not switched, then the locomotive will increase in speed.

If you are talking about the G-Scale shay, then go here:

I completely agree, just look at one of the other G-Scale manufactures, they have every single one on their site.  Why can't Bachmann do that as well?

Because of all of the complaints from frustrated Bachmann customers (who Bachmann (the company) should have been taking care of), I uploaded the 2-8-0, 2 truck shay, 2-4-2T, and the early 0-4-0T on here: http://hyaklocoworks.weebly.com/index.html

I have not had that problem myself, but here are diagrams:

Go to the Bachmann Gift Shop (link to the left), then under large scale you will see three different trucks.

The Consolidation uses the lower set of couplers (Truck mounted height).
