To know how many crossbars you have on your track:

You take the length of the track, for example 136’’. You must know the drive pitch, to do so measure between each crossbars, for example 2.52’’.

136 divided per 2.52= 53.96 You should have about 54 crossbars.

If you do a pattern 4 per bar, 54 x 4 = you need 216 studs.

If you do a pattern 5-4-4, for an average of 4.3 studs per bar x 54 = you need 232 studs

Every model is different so please check this before ordering. Thank you!
