How do you change a locomotive's top speed?
Thanks!

This would be done by changing parameters in the loco's enginespec, which is a seperate kuid number from the loco itself. The enginespec kuid number for a particular loco can be found in the loco's config file. I have not messed with enginespecs myself so I don't have specifics of what to change to get the results you are looking for.

Topt speed in DCC mode is defined in the motor section of the enginespec. Here is a snippet from SD40-2 enginespec,<kuid:-1:42004221>:

motor
{
resistance 1.7
adhesion 2.3
maxvoltage 600
maxspeed 35
brakeratio 55000

The maxspeed value is in meters/sec. 35 m/s is 78 miles per hour.
Maxspeed in cab mode is determined by the throttle-power section for diesels or the steam section for a steam loco. Some info on this is in the wiki at http://online.ts2009.com/mediaWiki/index.php5/Steam_container, however, I think it is currently down with a problem.

how would you change this so the loco would go at a top speed of 45mph

There is a good online units converter at http://www.digitaldutch.com/unitconverter/speed.htm
Using it 45 mgh = 20 m/s so edit the loco's enginespec motor section for maxspeed 20, then save and commit.
