Can't create cart with furnace in it to make a locomotive

Hello mr or miss

 

the other day I found a video on how to make a cart with a furnace to make a locomotive and I did look up on google to see if it true. I found out it was. I followed the introduction though it wouldn't create it

 

im using a ps5 to play the PS4 version of minecraft 

 

another problem is is it possible to make multiple save data as yesterday I lost my way back to my base cause I was looking for the blue orchid to make a light blue dye. Cause of this I lost many weeks of hard work of making a castle and train track 

 

I'll await to hear from you

many thanks
