Where can I get car repaired and where can I buy a new one

Can I hook up 2 number 4 switches together in order to connect two ovals of track and utilize my Bachman ez command system

Just got first set with dcc ez command. Would like a simple layout that will allow me to get familiar with ez command. I have a lot of of track and 2 number 4 switches, and another dcc set.
Thank you for your time.

What is the difference between these 2 switches.

Just got a Bachman set with ez command. Have 2 trains I want to run. Are there any retailers that have 2 inputs 2 inputs so I can input to ez controller. If not, what do you suggest.
Thank you.

Which switch should i use to connect two ovals of track. Will either be two 22inch track ovals or a 22 and 18.
Want to run two trains at the same time.
Thank  you/

Can I put a standard remote switch on a length of track that carries a train that needs 22 inch radius curves. I intend to make a loop that will have a 18 inch radius curve for a freight set.
My other part of the layout has 2 number 4 switches.
Thank you.

When I purchased my first set my hobby store suggested number 4 switches due to long passenger car and 22 inch radius curved track. I am now ready to expand and noticed there is no price differential between number 4 and 5 switches. What is the difference? Is the length of the track the same and what do you recommend. Thank you.

I am considering the Bachman Echo Valley Express to get into DCC. Set comes with ez mate couplers. Whats involved in changing these to magnetic couplers? Do any Bachman sets come with magnetic couplers ?
Thank you....

I have a Bachman Spectrum Acela express and am very happy with it. Now looking to expand into DCC and would like your opinion on the Bachman Echo Express that comes with Bachman DCC controller or getting a Bachman Spectrum loco and MRC explorer DCC.
Also, does Bachman make spectrum freight cars.
Thank you. New to Hobby.

Any comments on Bachman set 00503, digital commander DCC.

I now have a layout with 2 number 4 remote switches since my layout has 22 inch radius track.
I plan on adding another set that comes with 18 radius track. Should I only use number 4 switches throughput the layout.
Thank you in advance for your advice.

Any recommendations for a DCC controller or purchase a Bachman set that comes with one.

I have a Acela Express set that uses 22 inch radius track, I want to get 2 remote switches. Do I need # 4 or # 6 switch?

What is width of table I need to have 2 ovals , one with 22 inch radius and the other loop with 26 inch radius curve,

I have the above set that came with 22 inch radius track and a 45 x 80 oval.
If I want to do a inner oval, I assume it has to with 18 inch radius track,
I assume the Acela can not go over 18 inch radius. Is a option to widen my table and then make inner oval with 22 inch radius curve?

Just purchased a acela express ho set .every now and then the passenger train car coupler come undone. looks like a poor design?
