Bought first train in May.  Second train in middle of June.  Run trains when we open at 6:00 am to 8:00 pm.  I clean track one a week with damp cloth and then go over again with damp towel in rubbing alcohol.  I clean engines twice a week but probably need a oil to use.  I qtip the wheels with rubbing alcohol.  What oil do you recommend?  I am real A type when it comes to cleaning our system.  I don't know what type of engine is the bumblebee but would be interested in purchasing a higher quality engine that can take the hours of use on a daily basis.  Any suggestions?  Thanks for your help

Have a general store that we recently assembled a 130' foot train system for customers.  Our store is open 7 days a week and open for 14 hours per day.  I have purchased two bumblebee engines for our system and already the engines have given up the ghost.  I would like to purchase a higher quality, heavier duty engine that can withstand the hours of use.  Is there such an engine out there that can outlast the bumblebee?  Thanks in advance.  Kurt from Etna, Wyoming
