A continuación incluimos un fragmento del manuscrito escrito por W.H. Armstrong con respecto a esta sección del ferrocarril:
The R.R. to Lajas leaves San German on a slight grade which becomes very heavy grade 4 kilometers from San German. After following the base of the mountain for nearly a kilometer from the town the R.R. makes a complete semi-circle turn up a ravine around the base of a hill 150' high on its west side. The road is cut along the side of this hill. As the road makes its complete turn around this hill it passes kilometer 211 and a deep culvert, 6 feet long and 10 feet deep. From lik 211 the road passes S.W. up a ravine and then turns S. easterly along the side of a hill 300 feet high on its left or northern side. At kil. 212 there is a short retaining wall along the south side of the road 15-20 feet high. Half way between kil. 212 and 213 the road passes into the open where there is a low cane flat on the right or south side and a rising cane valley extending to the left or north. From kil. 213 to kil 214 the R.R. crosses a short culvert and passes a few low pasture hills on its right or S. side. The north or left side is low and rolling. At kil. 214 the road is covering its heaviest grade and makes another complete turn south and westerly around a hill 75 to 100 feet high. It then circles easterly between the hills to kil. 215 where the southerly side is open. Beyond kil. 215 where the road runs over a short fill of 10 feet, it then winds around another series of hills 300 feet high on the northerly side, then over a culvert 4' long + 10' deep, winding again around the base of 150' hills on the northerly side to kil. 216 where there is a short fill. There is a small narrow cane valley on the southerly side. Beyond kil. 216 the road winds around a low hill on its northerly side, to the town of Lajas. Trains stop at Lajas town but there is no station. The Lajas R.R. station is nearly a mile beyond the town at the junction of the Cabo Rojo branch where there are numerous long sidings and an engine house. The station is an ordinary wooden building. The engine house is an iron building that will accomodate 6 engines. There are no shops. This station is on the edge of the great cane lands.
